How do I install these kind of theft deterrant of my car,
should I put a hidden switch on my fuel pump, or in my ignition?
Both?

My car was broken into two days ago at my work place, the thieves didnt have time to do anything, since nothing was missing, my guess is that someone migh have drove by and scared them away before they were done w/the car.

What other kind of circuit can I bypass with a Hidden switch so that the engine wont start in case some one tries to steal my car?

I know that this question has been asked many times but no one has explained how exactly this works, or how to install them.
Diagrams of the wiring/process would be great.

thanks for the help.

 

just find your wires for your fuel pump, cut one put a toggle switch in and that is it, not that hard.
