Rear view mirror pinout

[brego]

I have a 2012 Tahoe Z71 and need pinout for the rear view mirror. Looking to hardwire a radar detector off the powered mirror. Hoping to find 12v that is on/off with ignition.

Did you ever figure this out? Looking to do the same to my '09.

Yes! Grabbed a multimeter to figure it out, saw the existing wires were color coded, so jammed the red wire from my detector's wire harness into the powered mirror hole that had a red wire, did same for the black. Works fine except its always on.

Awesome! Wish I had this a couple of years ago! Hopefully this will help some folks. Thanks for the pinout chart sir.
