Thats what I thought. Thanks My truck has Lane Change Assist, dealer and Gm says Tow mirrors and on LCA truck will not work. After they sold me the truck with a mirror swap promise. I don't care if the LCA works on the tow mirrors, i know it cant. But can i not just do the harness swap and fire the code that comes with the mirrors and turn off LCA? Any info would be greatly appreciated TIA

Bpgood1- Did you have to replace the wiring harness to? Im curios to know how you adjust both upper and lower mirrors with only the one button adjustment control inside ??? A new switch to? My dealer says they cant do it... thoughs?
