I did a real easy theft switch, take a extra floor 3 way dimmer switch, mount it up high on the firewall behind the carpet, run the coil wire to the common, a led on one pole and off to the coil on the other, when you hop in and turn the key on and the led is lit, you reach up with your toe, bump the switch, led goes off and you drive away, simple cheap and they won't find it easily, I read it in a magazine years ago. Best of luck matt
