I know this is not from a J, but it's going in a J...

I need the wiring pinout for an OnStar mirror, specifically the one out of a 06+ Cobalt. Does anyone have any idea? I googled for hours and found plenty of the older Gentex standard plug. It's the same plug, different wiring. It's a 16 pin connector, and pin 8 is ground (only black wire), but pins 1 and 6 are wired (which they were not in the old spec). Mirror has map lights and auto-dim as well if that helps...

Help!
