Car kill switch idea

[cb7ftw]

So most diy kill switchs I see, disable something. Like power to the fuel pump. Problem with that, they can be bypassed pretty easily. Was thinking it might be better to dissable something by grounding it out. What component would you ground out, to keep a car from starting?

If its some special car then maybe look around the forums to see if anyone is into the ECU. Twenty two years ago there were flashes available for the car I was driving where you had to tap the brake pedal three times or the car wouldn’t start (and other stuff like that).

In the end, if a professional wants it, they will get it. A locked garage is the best protection.

On some of the hot rod we build we put a Breaker on the “HOT” side of the computer. But this can fry you ECM if you do it incorrectly .

I had a Camry a while back that had a security system from the dealer where you had to flash your high beams and turn on your left blinker before starting the car. Sounds stupid, and who would steal a Camry? but I’m sure it would fool a potential thief better than a hidden switch. Just my 2 cents.
