Re: Need a Kill Switch

what do you want to have the cutoff on. Fuel is most effective in my opinion, and is this to complement anti-theft?

Yes. I see alot u guys on "Member's Profiles" complaining how your Civics are getting stolen. Right now i live in this small town( I'm in the Army) and next year i'll be finally moving to a real city. I don't wanna get caught with my pants down. Got any ideas for fuel?

Can some post a "how-to" on the fuel cut off, and or a starter cut off. PICS would be very helpful.

Thanks ahead of time.

Re: Need a Kill Switch

i have to go to class in a few minutes...but here's a bit of info:

next to the driver seat, to the left, running along the floor are a bunch of wires (they are under the paneling). Most of these wires are encased in a 3-4 foot sheath. Some of the wires run all the way to the middle of the chassis, so they are in black "tubing" stuff. To make a killswitch that cuts off the fuel pump, you need to look for the YELLOW wire, with the GREEN stripe. Now, take your average, run of the mill switch (whether you like flip switch, or push switch, doesn't matter) and wire it to the yellow/green wire. It's been awhile since i've done this, and we were working on a 2000 civic; but the whole thing works perfectly now. I'll see if i can get my friend to post up pics of the general process. His car is somewhat stripped and so it would be pretty easy, but no promises (he's a bit secretive, for good reason, about this stuff).

fuel kill switch

problem with a push button is if it's a momentary push button as soon as you release the button the fuel pump will stop. a STSP switch is the best to get.

wiring it up is simple cut the yellow wire with the green strip going to the fuel pump and connect one end to one terminal of the switch and the other end to the other terminal.

stuff you need to watch out for:

1) the yellow wire not being long enough to place the switch where you want (solution solder extension wires to it)

2) the switch has 3 terminals (solution solder one wire to the middle terminal and the other wire to one of the (and only one) outter terminals. )

3) the switch has 4 or 6 terminals (buy a simplier switch)

anyways the install is about an hour (including time to let the soldering iron heat up). PM me if you want help with it.

Re: Need a Kill Switch

kill starter doesnt do much, if someone can get into your car, and if your car is a stick, all they can do it push start it and it starts right up. invest in the club for the steering wheel and the one for the pedel.

what i was thinking of, is putting one in d cigaret lighter i had my car for 11/2 and never use it so cut a little from d top of d casing with a dramell just enough were u can switch it with one finger and sand it to take d rough edges off ,than a hard adhesive to put it in place or tie wraps d small kind i will need a bigger gauge wire do since i got to take d voltage resistance into account but ill let u no how it goes...is just an experiment so i will do it in a dummie lighter first that pick at a junk yard

Re: Need a Kill Switch

Fuel cutoff is the most effective by far. I tapped a switch right off the wires leaving the fuel pump (its underneath the back seat in that silver oval). When the switch is activated, my 99 Si only runs for 2-3 seconds before it dies, I couldn't even get it in gear in that time.

Re: Need a Kill Switch

Ok, here is what I did for fuel cutoff. I refered to page 11-236 in the helms manual, this if for a 96-00 civic.

I removed the backseat, upper and lower parts. I also removed the drivers side rear panel to run my wires to the switch. You will see an large aluminum oval dead center, the fuel pump is under this. You can take off the aluminum cover (4 screws), but there really is no need to. I just took the electrical tape leaving the cover off and pulled the wires out. Find the Yellow wire with a green stripe, it is one of the larger ones. Cut your wire and you will be sending each end of that to a switch. Use 16 or 18 guage wire leading to your switch. A relay can also be used, also optional, but i didn't use one.

I hid the switch in my trunk. But that is because my trunk was modded for only remote pop. You can put the switch anywhere, you can even have two switches for extra security. I prefer tapping the wires strait off the fuel pump, because ECU tapping is easier for a theif to work around. They aren't going to be taking out your back seats, at least i don't think so. Let me know if you need more help with this.

Re: Need a Kill Switch

Here you go, this was a post I did on another board(you can ignore part one, I just cut and pasted everything).

Part 1

So last week, I was able to get a set of autometer boost and a/f gauges from AWD 4G63 (thanks again)





Since it was a nice weekend, I decided to make a gauge holder for them. With the gauges in hand, I chose to throw them in the compartment near the cup holders. So I took out the cup holders and went on a quest for ABS plastic.





After hours of searching the south burbs for plastic, I found none. Everyshop I talked to had to order it. So sad and beaten, I stop by my dad’s shop and then it had shown itself. In the back was a discarded chevy cavalier front-end. I looked around and found the fender moldings. So bare-handed, I ripped them out and cut them to shape. Then I riveted them to the cup-holders and the DIY was near completion.





Once the molding was in place, I cut somes holes in them, put the gauges in and threw the bad-boy back in the car.





All in all, $2 for extra wires + $2 for connectors + $0 for cavalier molding =



Part 2

Well, being the loser that I am with mucho free time; my weekend was not done yet. So I decided to make a fuel-cutoff switch. With that in mind, I headed back to Radio shack and picked up a rocker switch.



Then I found my fuel pump power wire



and made a slice. With some male and female connectors, I attached it to some wires and ran it to my hidden switch.



So for that DIY, $4 for the rocker switch + $2 for wires + $1.50 for male/female connectors = a $7.50 security system that rivals many high-tech ones. With the hidden switch in the off position, no power to the fuel pump = no fuel to the engine = no moving for the car.

Re: Need a Kill Switch

And even better solution than that just listed above is this setup here ....


It will cost you about 20 bucks for all the materials, and there is no "hidden" switch like in the one above.
The switch to enable the circuit is a magnetic reed switch, so unless this thief happens to be carrying a magnet on him, forget it. If he could even find where the switch is located. It can be virtually anywhere on your car. If they were to know where it was, it could be bypassed without a magnet, but would still be a lot more difficult than the above description. You would have to know what wires did waht considering you would ahve 4 to work with. As a matter of fact, because of the way the reed switch works, I'm not sure if there is an easy bypass. I will have to investigate more.
The cutout described above is just a simple toggle switch, very easy to find, and very easy to bypass.

Very nice design and works great. I installed it a couple weeks ago and it's da shit! Between this and my Alarm, I feel much safer about my car being stolen whilst I'm at the movies, mall, etc...

Good Luck!

Re: Need a Kill Switch

Can you use a Heavy Duty 12-Volt Horn Relay for that project? And.... Why not do the switch and the magnet thing? Double it up, then it'd be really really tough, those two + alarm? But mostly... Can you use a Heavy Duty 12-Volt Horn Relay for that project? And I may just be slow but... does that magnet project look tuff or is it just me? I'd like to know how to do it though. Also... what gauge wiring would a person use?

civicgeek9
(Jr Member)
10/24/03 09:14 AM
Re: Need a Kill Switch

Okay here ya go for the magnet style relay cutout. Some more details and information....

You will need the parts listed of course.
Get the Heavy duty auto relay, a must have for making that connection into your fuel pump. It's a high current/high voltage application, and can handle the amperage running thru it for prolonged periods of time. Which is something you will want when wiring into your fuel pump's power line.
For the DPDT relay, the relays i was able to find at Radio Shack where like 10V only. You need a 12V DPDT. At least that. And the reed switches at radio shack work, but are very low amperage as well. I'm still trying to locate better ones to use. Fry's was out of stock when I was there last. But they do have nice DPDT relays @ 12V and like 10Amps, perfect for this application.
Cars run 12V (duh!) and about 6-9 amps of current normally. Dependind on device being powered. So you need devices that can handle these currents. Now the reed switch will only be a temporary passage of power, so it's okay if it's amperage is lower, but there is a downside.
Sometimes, the circuit doesn't want to set when you first pass the magnet over it. You will hear the DPDT relay chatter, trying to go into the set or locked state so you can drive. It's not that bad of a setback. I wired it up anyways. It just takes a few passes of the magnet sometimes to get it to lock. But most of the time it works first try.
So you might want to try higher voltage and amperage DPDT relays and reed switches. until you can find one that works better. I don't mind if it gives me problems every now and again, I can deal for now until I get a larger reed, which I believe is what is causing it. Cause If i played with the circuit w/o the reed, it worked every single time with no chatter.

The schematic is so-so at best on that diagram. But it's actually quite simple. Just make sure you SOLDER ALL CONNECTIONS!! You don't want shit coming loose or touching and blowing something up. I am working ona better pic to post for all of you. It will make wiring that circuit much easier for those that aren't electrical engineers when they go to work. I got lucky, i know this shit, so it was quite easy for me.

I used my center console for mounting of a lot of the pieces, and then ran wires to my reed switch location. Then put the auto relay under the seat, try to use 6 inches at most, for the connections that you splice into your FP power line that will pass thru the relays input and output. Again, you don't want to loose voltage or amperage running into your FP motor.

I will post a schematic later after I get it finished for all those interested.

Materials can all be purchased at yoru local Fry's or other electronics store. Again, the shit available at Radio Shack isn't all the best. I think i used the Auto relays and reed switches I got from there, and that's about it. But I'm still looking for better reeds before I install this same shit into a friends car.

As for "doubling up" the circuit, this is possible, anyone want to take a crack at designing a circuit for this guy? I find that the one in that link and that i used is definitly enough for me. I mean, w/o fuel, you're fucked. The car can and will sometiems start, but die in about 30-60 secs at most. And if you're driving and it accidently trips, which mine has only done once in 3 weeks, you simply pull over and reset teh circuit. It helps to have another magnet hidden in the car and easier to get to than tha one on your keys.
Like anyone is going to know WTF that magnet is for stuck to the bottom of your seat!?!?!


If anyone is really interested in having one of these and not wanting to take the time to make it and all that. I am accepting $50 via paypal to make them for you. Materials cost me 20 bucks and then 20 bucks for my time and effort to make you a harness and 10 bucks for Fed Ex/UPS shipment.

PM me for more details. But please, I am still searching, so it may take me a couple weeks. Once I have located all the parts in a better stock, I can make them much faster and more of them. Right now I have only been able to scrounge up anough shit to make 2 more.
Prolly going to have to order the shit in bulk from somewhere.

Re: Need a Kill Switch

okay so i made a new schematic for those that don't quite understand the last one.
I went and pulled apart my shit to verify everything.
If you have problems making thsi work. I am sorry about that.
Mine works just fine, except that reed switch and chattering problem I mentioned.
But I did learn, that if I hold the magnet, so that the flat surface faces the reed, instead of the small edge, it works 99.5% of the time on the first try.

Good Luck to all those that give it a try. I love mine!
Schematic... (sorry about the shitty resolution, it's hard w/o a scanner. And a digi cam pic just isn't the same. But it works. )

a sample of the goods....


one last thing... Radio shack sells little square magnets with a hole in the center that fits nicely onto a keychain if you want to do it that way... I just didn't want to carry around 2 alarm remotes on my keychain... I like my keys as light as possible. Also be sure your LED you buy is a 12vdc LED as well. If not, it will blow up as soon as you apply power.

Re: Need a Kill Switch

I did my own little schematic drawing.. not realizing that one had already been done. If you can interpret my drawing at all (I know it's not electronically correct) I used a two sided LED that will light green on one side and red on the other. The schematic that I drew will cause the LED to light green when the fuel pump is active and red when the fuel pump is disconnected. Also, as was alluded to above, the two-color leds are NOT 12v and thus need a resistor to keep the power down, the exact resistor value will depend on which LED you get, but the one I purchased required a 333.33 Ohm resistor.

Hope this helps someone

Here it is. (PDF)

Edit: After reviewing my circuit, I need to make some modifications. Pin 6 needs to be tied to ping 7. (critical..or the damn thing won't work) And a co-worker suggested tying pin 4 on RELAY_DPDT to ignition power so that when you shut off the car, it automatically collapses everything and your fuel pump is disconnected... only bad thing about that is that you have to have your key in the "on" position for the whole thing to work. This means that if you have to have the magnet OFF of your key right
Last thing: The momentary switch on the bottom that's tied to pin 8 should be a normally closed... I forgot to specify/draw that. I'll leave that link up, but it will be revised this evening.

I met a guy at the dealer getting parts for his stolen Civic. I was talking to him about how my Si was broken into several times. We discussed if he had an alarm and he said he did. He even took out the ignition fuse and they replaced that and drove off with his car in his driveway. Thieves are getting smarter and carry their own fuses. Just an FYI.

Re: Need a Kill Switch

Well.. I finally did this last night (the magnetic version) It's FRICKEN AWESOME. I rigged it up so there's a green light when the fuel pump is active and it turns red when it's disabled. I ran into one big snag though. I had run the wire from behind my dash back to the fuel pump and I kept popping fuses on the +12v I was tapping off of. Finally, 2 hours (and dinner) later.. I realized the wire I sent to the back was laying on the metal where the seat was.... *grounded* so when I applied power: POP! Stupid wires... so here's my tip: use electrical tape around EVERYTHING... even if you don't think it needs it.

Magnetic method isn't hard at all, just follow the diagram. It does take a bit of time if you're not too practiced at this stuff, but is not hard at all. If I weren't too lazy to unsolder my LED I'd do the red/green LED thing too, but for now just red will have to suffice

i used 14 gauge wire, but i did the switch way, not the magnetic way. didn't have to use a fuse as long as the switch was high enough in amperage. the switch one was really easy. i didn't want to do the magnet one, even though it's a really good method, i didn't feel confident in my abilities to do the work. good post.

Re: Need a Kill Switch

And FYI ... there are alot of proponents of fuel cut switches.
I'm a firm believer that a switch somewhere in your ignition system, IE somewhere between the key and spark plugs (lol vague) is just as effective if you do it right (albiet at the risk of flooding your engine).

It's saved my dad's '64 StingRay twice, his '84 RX-7 once, and just saved my Civic last week.

They broke in, jammed a screwdriver in the ignition switch, and cranked. Nothing. My car remained. Minus $700 worth of shit stolen of course.

It was so effective and inconspicuous on my Civic that when it went to the repair shop (long story) ... and they began repairing my car WITHOUT MY FUCKING AUTHORIZATION (lol uncontrollable rant), they replaced the ignition switch, and it SHOULD have been starting properly. I was told they actually went and bought a new ignition coil, BECAUSE THEY COULDN'T FIGURE OUT WHY MY CAR WAS STARTING.

If a repair shop can't figure out how to start it, it must be good.

No you do not need more solder, you need a CLEAN solder.
If a solder fails, it's cuz the connections you were soldering were dirty or soiled in one way or another. Try using some alcohol on the wires and terminals before you solder it. Wash and dry your hands really good, and touch the wires, etc, as little as possible before applying solder.

I just visited this thread for the first time since I posted my original schematic... I am VERY happy to see that a lot of you have been able to follow it and do one for yourselves. Congrats to all who take the steps necc to protect their investments!!

And to DanialSmith.. Nice work on the dual LED setup.. that's pretty nice as well. I might have to add that on to mine when I get back home from Mass on business.

Good job everyone! Stay safe and secure!

Re: Need a Kill Switch

HELP ME PLEASE!! I followed the instructions perfectly, TWO TIMES! and it still pulls constant power somewhere. There were no wires grounding out in the first setup and there are none in the second setup! Can anyone help me with this? Are there any small specs. in the equipement that I had to look out for? Did I make a wrong purchase for parts? I just dont get why it constantly pulls power, even when not activated.The only thing I've thought about is that the wire going from the fuel power line to the relay or whatever is pretty long, could that have any posibilty of being it? Any suggestions, please!

When you guys installed yours, did it kill your battery? None of the wires are shorted on mine, but the reed is pulling a constant... .1xx volts. Over a short period the battery dies. Is this happening to anyone else? Could it be a dead piece of equipement? I replaced the reed but it still does it.

It works for me, I don't have any problems there. It just pulls constant power and over a period of a couple days kills my battery. Theres a small pull somewhere in the system, none of the wires are grounded. I checked and there was like, .13 volts running to the reed at all times. I can't figure out why its constantly pulling power.

BTW.. for everyone.. I am not sure what his problem is. My reed has a constant 12V input, as well as the coil unit, like in the schematic.
I have left my car for about about 2 months before and it never drained my battery.
The LED is the only thing drawing CURRENT from your battery that will drain it. As for 0.13 V draw.. That is pretty much 0. That is most likely the draw from the meter itself, not just the wiring. But it would prolly take like 6 months if just sitting and never recharging. Which could be your problem, you have a weak battery? How old is it?

Not sure what else to tell you. I have never had a problem with mine. :shrug:

why don't you just buy an alarm. There is an alarm that when ARMed you cannot start the car, and if someone tries to hot wire your car or use a different honda key (this has happened to me) while ARMed it will kill the starter and you would have to reset your computer by unplugging your battery to reset computer.

So it makes it to where you have to disarm the alarm in order to start your car. It is really cool and it works, my buddy has it on his prelude.

sorry about my post earlier. i didn't have time to elaborate because i had to head off to work, but anyway...

before i start explaining, i'd like to say that it has not been installed in the car yet, because i wanted to test it out. i hooked everything up and soldered the wires where needed and tested the circuit in my room. everything looks good and works okay and i bought all the parts from RadioShack.

when power is first supplied to the circuit, the LED goes on. well when i slide the magnet over the reed, the LED light goes off when the magnet is closeby (which it is supposed to), then as i move the magnet away, the LED light comes back on (not the way it suppose to be. the LED light should remain off, as the only way it suppose to come back on, is if i push the push button).

everytime the LED light goes on or off, you can hear the 10A plug-in relay clicking inside. this let you know that it is working, and you can visually see the metal connector inside the relay moving, so i know that the 10A relay is working.

one solution i found to work, is if i don't slide the magnet over the entire reed, but to just point and pull away at only one end of the reed with the magnet. by that i meant putting a magnet close to one end of the reed (the black part of the reed, with the 3 metal connectors coming out of them) in just that one area.

if i slide the magnet near the other end of the reed (the black part of the reed, with just one metal connector; that's the one that needs to be grouned), then the 10A relay will just keep clicking for as long as the magnet is over it.

another weird thing is that if the LED light is already off and sliding a magnet over that particular end of the reed (the one with just one metal connector, like i said before), then it will turn the LED light back on, so in essence, the reed can do both work, and that would defeat the purpose of having a push button to re-arm or disconnect the fuel pump wire. that's what i meant by reliability. you don't want to accidentally disconnect the fuel pump wire when you're trying to re-connect it.

---

besides this, i was wondering if there is a way to wrig up something similar to this wirelessly. i was thinking of using IR or radio. i like the idea of installing a kill switch, without running a set of wires from the back of the car to the front, thus making it even harder for thieves to trace the wires.

Re: Need a Kill Switch

I ran my wires all over the friggin' place, so hopefully they won't take the time to figure out how the circuit works. When my car was an attempted theft, they didn't. Fuckers. Anyway, I believe that's how the switch works (correct me if I'm wrong), one polarity of the magnet will turn it on, the other off. Either that, or you have a grounding problem (if your switch will not stay set). I followed the diagrams exactly and mine works perfectly. Maybe someone more electronic-oriented can help you out, best of luck.

Re: Need a Kill Switch

if it's set up properly... there shouldn't be a chatter sound. you've probably crossed some wires some where along the line. if you hookup the NC side of the relay up to the power, it can engage/disengage really fast... causing that sound.

Re: Need a Kill Switch

i know you guys are probably tired of me asking this question, but i went back to radioshack and re-bought all of the parts and redone this kill switch cleanly. i know that i didn't cross any wires at all in the installation. when i hover the magnet over the reed, the LED lights goes off and when i pull the magnet away from the reed, the LED comes back on. WTF??

i checked all of the wires and i don't see a problem at all. i've even tested the Automotive relay (connectors: 30 & 87) on a simple 12V light bulb, and it works when the LED is off. all wires have been soldered. i've redrew the same schematic, according to how i hooked everything up here:




now here are some pictures of the individual parts i put together using my webcam:

the reed (front / top):




the reed (back):


the momentary pushbutton:


some pictures of the Automotive relay with the DPDT relay:






okay. i narrowed down the probem to the reed. i switched my new reed, back to the old one and it still has problems.

***edit
i'm using a normally open reed and i think that the metal connectors inside the reed does not stay closed when a magnet passes over it.

Re: Need a Kill Switch

whoops. i meant normally open. it was really late when i typed it up, but anyhow, i'm gonna give this one more try, then call it quits and go with a regular kill switch. i've wasted too much money and time on this project, but it was fun. i burned myself a few times with the solder and cut myself a few times with razor blades.

yes, razor blades. i was working on a different car security project prior to this one and it involves lethal, but not deadly razors. lol, i guess i'm paranoid, because i live in the ghetto (that's what my friends call the area where i live). anyhow. i've attached double sided razor blades (the ones that you can buy at your local Walmart store) to the underside of the doorhandles, so that the theif, or would be theif, would cut himself. yea, i got two deep razor cuts on my fingers from forgetting that i have razor blades underneath the doorhandles - lol.

i've also started to mod the air vents to shoot out razors when the ignition is on, but didn't quite get it to work perfectly, mainly due to the part that i've already cut myself twice, and because i might accidently hurt someone i care about. in the first case, i used rubber bands to propel the blades; not reliable, and doesn't shoot straight. the second case involves modifying my paintball gun to use airtight hoses to shoot out the blades; too fast & deadly, plus it will ruin the seats.

sxng9, your setup looks WAY more professional than mine, you must just be having a simple problem in the way it is wired.

I can tell you from personal experience that this setup is worth it, and if you spent anything less than a hundred bucks or so then I wouldn't worry. Mine has cost me about 20-40, and that's after having to redo it due to a theft attempt. The first time I set it up it was around 20. Have you tried turning the magnet around the other way and putting it close to the reed? Have you made sure whatever you're using as a ground source is actually grounded?

(and many other projects) In addition to parts express I usually shop at a place called Gateway Electronics here in San Diego (no relation to Gateway computers)

As for the problem with the cool new schematic. It makes sense that it's not working, I'm just trying to figure out how to explain it without confusing everyone. I only used 2 wires from the reed switch and I didn't really follow that previous schematic at all But give me a few minutes and I'll see if I can figure out your problem (or offer a solution)

yea, haha. i guess i am sorted impressed about this kill switch project. i spent a lot of time on this. i'm pretty good with electronic things, so i know that's it's not anything electrical. like i said in my previous post, the main problem is the reed.

there are 2 factors that contribute to the problems with the reed i bought at Radio Shack:
1) the polarity of the magnetic side on which you use to slide over the reed.
2) the glass tube inside of the blue casing, needs to be adjusted.

i'm trying to push myself to get this finished before i go on vacation in July, but if i don't, hell with it. oh, also, one of the funniest thing i did the past 2 days was i went to every single radio shack store where i lived and bought every single reed they had, due to breaking so many reeds.

as for the proper wire guage, 14 is good enough. for my project, i used 14 and i think i used 16 for the circuit board & around where im running wires that are less than 5 inches long.

the thing is, don't make it sound more complicated than it really is, and always be sure to test it out on a bench to make sure it works the way you want it, before you rip the car interior apart and drilling holes.

I took it off the big fat white wire running up to the ignition because it was part of the ignition I actually soldered it and wrapped it, loomed it, etc, etc. Just wanted it to be really nice.... if you go this route, be careful soldering up there as there are a lot of important wires there

Re: Need a Kill Switch


This is my revision. I'm assuming that 1 & 2 on the DPDT relay is NC and 3 & 4 are NO. The idea is that when the relay is engaged +12 is put back into the coil

Re: Need a Kill Switch

i still don't know where you bought the reed relay, and i had a hard time finding one that works, so i decided to wrig up a remote wireless fuel pump kill switch. i found somebody who was good with building wireless stuff, so i had him build me a simple control unit, and a simple remote.

the remote has a good range (maybe half a mile??) - j/k; i tested the control unit from the basement and tested the remote from as far as the very back end of the fence in my backyard. it might even have a farther range, but i have yet to test it. if i'm ever at gun-point when in the car (or out of the car), i can push the button on the remote, and no, i don't keep the remote chained along with my other keys. i keep the remote elsewhere on me, so i can cut-off the fuel, even when the theif is far away from me.

besides the remote-controlled kill switch, there is also a simple manual switch hidden in the car. i bled my hands to death trying to hide everything, so i hope that what i have done so far today was worth it.

as far as the schematic, it's basically the same as the reed relay kill switch, but just think of the DPDT Plugin Relay as the actual control unit. i'm still using an automotive relay, but i took out the flashing LED, the reed relay, and the pushbutton.

...well the pushbutton is still on my car, but it's not hook up to anything, and serves no function, other than to fool the theif. i already drilled a hole in my car prior to building the remote kill switch. i might as well leave the switch there to fill in that empty hole, and to fool the theif, that the switch actually does something, until when he rips the dashboard apart.

Re: Need a Kill Switch

Just installed my first fuel pump kill switch today. And I jsut discovered this thread. My friend did his and told me what to do. I wired it next to the kicker panel. It is a yellow and green wire you splice into. I might do another one by the rear seats.

Hey guys, I bought all those parts that you need for the magnetic kill switch, but I have no clue how to wire this up, this is a pic of what iv got:

Thanks for your help!
The DPDT relay looks the sameas the pic above, but the regular 12V relay is different, on my 12V auto relay it sais 30,85,86,87a,87, and from my pic is the magnetic switch good enough???

Re: Need a Kill Switch

I'll probably be installing a kill switch soon too, although I think I'm going to tap mine from the clutch switch which only lets you start the car if the clutch is fully depressed. Then, the car won't even be able to crank over or anything

Does anyone see any downsides to this? I mean, I'll probably wire loom all the surrounding wires so that nothing looks out of place under the dash. Then I will have to find a good hiding spot for the switch, but other than that, I think it should work better than just tapping the fuel pump power wire...

Re: Need a Kill Switch

just pull the main relay out. its under the dash by the steering wheel shaft. its a 1" X 1" X 2" box with a plug and about 8 or 10 wires running to it.., and its the relay for the starter, fuel injection, and pretty much everything else your car needs to run. i cut the clip for the plug off on mine, and it only takes about 2 secs to pull out.

Re: Need a Kill Switch

nice thread guys.

I just did one today.
1. Just cut the yellow/green wire in half. (I wont say where i did mine)
2. Bought some male/female quick disconnects from radio shack
3. Bought a 25amp 12VDC SPST rocker switch from radio shack Rocker
4. Bought some 14 gauge wire from autozone
5. Put a female (or male) quick disconnect on each side of the cut yellow/green wire
6. Put a male (or female) quick disconncet on each of the 2 lines of 14 gauge wire.
7. Plug the 2 lines of the 14 gauge wire to the 2 lines of the yellow/green wire useing the quick disconnects u just put on.
8. Run the 14 gauge wires where u'd like.
9. Put female quick disconncets on the end of the 14 gauge wires
10. Plug the female disconnects to the 2 male ends of the rocker switch.

Done! Just make sure to crimp everything well & use electrical tape. My way is not complex, but it does the job. I have almost no electrical knowledge at all, but I was able to figure it out, so anyone should be able to do it.

The hardest part of this is taking off the interior panneling.

Re: Need a Kill Switch

Dont use LEDs, if i was trying to steal your car i would just fallow the led wires to your switch rip the wires off it and twist them together. Thiefs arent stupid these days the magnet switch isnt really going to help because you can just rip the wires out and twist them. Real car thiefs are not going to be stoped by a magnet switch. The key to this is hiding the switch and the NONSTOCK wires going to it. Taking the main relay with you is pretty good, you can also take the ecu with you if you have a gutted car. Removeable steering wheels. If it takes you less than a whole day to wire your alarm and kill system up then your not hiding this stuff enought. All hondas have the wires in the same places, its not that hard to trace. Another excelent option is a hood locking system so that they cant get to the battery and horn. also hidden gel cell batteries and hidden horns are good to. But the sound that the horn makes gives away its location to makes it damn hard to get to. Any car is stealable you can probably come up with a system that would prevent is from being driven away, but it can still be stolen. I heard a story about one of the first porsche 911's of a certain model, the car was behind a 12 foot tall wall in a compund with a locked gate. car had a full system and everything. they used a crane and lifted the car over the wall and droped in on a flat bed truck.

Im not sure if ur replying to me or not. But could u elaborate on not using led's. i though those were those little red lights. but u said a theif could follow the led wires so Im not sure what that means.
but anyways i didn't use an led switch so i'm not even sure if u were replying to me or someone else.

You don't need a key to pop the trunk or fold down the back seats, even if it is "locked"... apparently you didn't know this, but theives do. Theives know A LOT more about your car than you do.. The more we teach the owner about their car, the better they can protect themselves from the theives. I assume most theives don't get their info from the internet, their info comes from just knowing the vehicles they're working with.. Most of the "security" features of a civic is just a peice of plastic in the way or a wire to short..I didn't learn this from the internet..I learned it just from working on my car.

Anyways, I am truely sorry to hear about you loss.. On april fools day too, thats fucked up.. you must have thought it was a bad prank untill you saw what was left of it..

Well I installed my kill switch today and i feel pretty good about it. I was a little bit more comfortable at work today!!! I do not feel right telling anyone where I put it but all I can say is, be creative and really think about where you put it. I instaled mine thinking of the same thing like 50 times, "No I bet the thief will check here from experience" before I actually found the right place!!!!

Good Luck peps!!!

Best - Quick Release Hub
Better - Club and Brake/Clutch Lock
Good - Noticeable device on the Steering wheel

Re: Need a Kill Switch

This type of kill switch used to work back in the day. But it is not played out and real easy to bypass from the start. The best way to install a kill switch on a honda is to do it from the main relay. Reason is because with the way that you guys are doing it. If I was a theif I would just pull 12 volts from the cig and tag it straight to the fuel pump if I did not hear it prime. Ans yes theives are doing this. If you kill the ground on the main relay. You are really doing 3 kill switches in one step. This kills the fuel pump, Fuel injectors and part on the ecu. There is then no way to hot wire the car. I also like to relocate the main relays when I do alarm installs to keep the theif from getting to it. This should be the way it is done if you really want to protect your car. The best thing is that all it takes is a 1 amp switch to do. Or 1 relay to have the alarm do it for you when you arm the car.
