OK...I just had a look and the shop removed the resistor I put in and put the wiring back to original. So what went wrong with my mod ? It was a 1.5k resistor I used. I cut the yellow wire while the car was running, and soldered the resistor to the half leading to the ignition switch and the other end of the resistor to the stripped black wire. I put a shrink tube on the loose end of the yellow wire. The theft light remained on for a few hours but was out the next day when I drove it. It started for 2 days and then quit. I thought once I cut the yellow wire the anti-theft was disarmed. The only reason for the resistor was to keep the light out. Right ??
