Does anyone have this. I picked up a auto dimming/compass mirror at the junkyard. I've figured out a couple of the wires, but would like to know what the rest control so I can get as many things work work factory as possible. If you could just tell me what the color codes are.

I have the mirror without onstar, just a "N"orth button in the bottom center and maplights on the bottom.

Thanks.

 

Here are the pinouts for the DD8 inside rearview mirror. The info is direct from the Chevy Service Manual. I've omitted the info for the OnStar.
