hi i know it has been a while but just an update here from my 2022 AT4X DQS add.
I successfully installed the tow mirrors and now the door harnesses (took a while to get the door harnesses from gm).
The power fold works along with the heat, power adjust, work lights
The camera angles are off i have to wait until wmas can adjust them not a big deal hopefully soon.
But the clearance lamps, turn signals, and back up illumination lamps do not work.
I assumed the turn signal would work because i had them on my factory mirrors but they don't any ideas why ?
I am going to try giving boost auto parts a call today see if they can help me out at all.
