Ok, my dad gave me this idea. He did it with his 60's Vette (in the 60's). he ran a switch for his fuel pump behind his seat. So if some1 tried to start his car, it would run (well, his car was carb so it'd run for a min).
But think, you can put all the alarms on your car, but they know how to get by them. Run a switch or a fusable link somewhere that you can get ahold of fairly easy but for the bad guys to figure out.
just a tip for you honda/acura guys that keep having problems and are afriad of ur baby gettin stolen.
