bought a ProForm adjustable shift light. any idea which wire to tap into? i am braindead, help me out here. it wants a ground, a power, and a signal... where is the signal? heard something about a blue wire on pcm, pin 10 or something.

 

The signal wire is the RPM or tach signal wire coming from the PCM. I do not know the pinouts of the PCM, nor the color.

But I bet if you searched harder in other sections of the forum, you'll find your answer.

 

white wire coming out of the cluster

 

white wire? cool, appreciate it.
