My head is spinning after reading about 30 pages of this thread.
Ive been looking to upgrade to tow mirrors from my current non signaled/non power fold, but heated/power glass mirrors on my ‘16 Chevy 2500 LT 6.0 gasser(midnight hd if that matters) for some time now. Since I started researching a yr ago, Oem harness #’s have changed. Truck side I do have all the correct pins for the applications I’d like including puddle lamp, turn signal, power glass, amber running lights. After seeing the 1A auto issue, I’d rather stick with GM mirrors. I’d gladly purchase from you Phill if I need a certain custom harness? Any and all input is appreciated guys, thanks guys
