My dad wired up a "rig" on my vette years ago that was in the glovebox (locked) that I just unplugged 2 wires and left them in the corner of the glovebox. If they weren't plugged together, the car would start as long as the key was in the start position, but as soon as it was let loose and returned to the run position it died. Saved it once!!! Someone broke into the car, stole my stereo and some tools, jimmied the ignition but never got it started!!!! Just hide something that cuts the ignition, should be good. Glad to hear the scumbag didn't get your car!
