Local theft in my area has made me weary my car is at high risk for theft. So I'd like to do some work to make it harder to steal. the location of my switch will remain unknown, BUT, whats the safest way to install one without having to use a lot of hot current wires? I was reading and it looks like possibly make a ground on the ECU for the injectors so they wont fire, but thatd require 4 seperate switches, are there any better methods?
