Thanks for the reply! That is what I was looking for.The 89 to 01 camaro use the same vats/passkey wiring setup as the 95 GP but a different pcm. Most people disable in programming but this is obd1.5 so not a real option.Now I know the direction of the current and the destination. I haven't found an pcm pin out for it. It has 3 square plugs going into 3 separate corners on the pcm.The BCM is by the drivers left foot with one pigtail I can see. Could I cut the dark blue wire at the bcm,cap the pigtail end and attach the signal generator to the wire that would then run to the pcm? Assuming the wiring on a w body isn't the problem. lol
