Can you post that one? im thinking of using mine for a power switch
Gotcha covered Matt. Dan, don't know if this will help, but I suppose it's worth a shot.
Btw, Matt, if you're trying to run an accessory off that wiring it may not work. I tried running the power and ground for a video monitor off that with no success.

Yellow/black - Keypad Green LED signal
brown/white - Keypad Red LED signal
turq/white (dark green/white???) - Keypad signal
green/black - Keypad supply voltage

Sorry to resurrect a 10 year old post, but I recently got a 2002 Tahoe and have to replace the stereo. I want to retain as much factory stuff as possible, and the OnStar diagram you posted is the best one I've found. I had thought, and lots of other sites implied, that OnStar is connected to the stereo. But from that diagram, I don't see a connection at all. The one question I have is, if that's the case, where does the OnStar voice come from? I ask because I don't see a speaker in that diagram, either.
