Glad it was so easy. So next time that kinda question comes up.. we've both learned how to get it going!

It's one of those things though...look at it and realizing the pcm uses ground vs power so it doesn't have to conduct much, and then that it uses a ground to turn things on/off like the light. All GM would have done is splice that light off the wire aiming to the pcm and poof.. accomplished two things with one wire.
