Have a 2008 Impala with auto-dimming rearview mirror with onstar.
Need a pinout diagram or wiring diagram for the wiring pigtail that
conects to back of mirror. Can you help?

I could probably lookup the pinout for the 2001 Impala I had with the auto-dimming mirror with OnStar if you think that would help.

 

I have no idea about the wiring, but in my 2014 impala this is the first time I've had an "auto dimming rear view mirror"....

Let me just say that in day time - when the sun is in the rear view mirror - as happens on more than one occasions around here - nothing happens that I'm aware of.. and I'm wearing shades...

Can't block it out by pulling the lever... because there is none.

Any one else dealing with nazca lines by your great leaders?
