the other day i was pulling a honda accord into work, and the car wouldn't start unless the defogger switch was on. a neat little trick, but also a "decent" theft deterrent. anyone ever do this with their car? i'd like to do something simular with my integra. how do i do it?

It's jsut a kill switch hooked up to the defroster I'd imagine. Do a search for fuel pump cut off and you'll probably find your answer

Yeah, it probably disables some vital engine function like fuel or ignition.

If they really want to steal your car, they will put it on a flatbed.

haha, that is true, i just wanted to learn a new electrical trick, thanks

another good 1 is throw in a relay to your starter wire in the normally open config and then have the relay close with the push of the horn, simple wiring and who is gonna honk the horn to start the car in the middle of the night.

that could piss the neighbors off, besides, they'd get used to it, and wouldn't know if it was me or a theif, lol. that is another cool idea though

Sounds like it's just a kill switch wired to the rear defogger. Pretty smart, the only downside is that you'll have to leave the rear defogger on while you're driving

I have a How to on my website. i have used it many times. you can hook it up to any switch.

this is correct information.^ the only difference is the activation wire was hooked up to the defogger. and no, you won't have to keep it activated to keep the car running.

it might not be a fuel cutoff switch; instead, it might be a starter kill switch. the difference is that the fuel cutoff will require your button to be in the "on" position while the car is running. a closed circuit must be maintained if the car is to remain running.

the starter kill switch just needs to be pushed to start the car. after the car has started, you can release the button (to the "off" position) and the engine keeps running.

to me, the starter kill button is just as useful and less risky since you run absolutely no risk of your engine turning off while driving b/c of a faulty relay/button on your fuel cutoff circuit.
