Let me start by saying I have a 2015 Denali 2500HD. I had the plain black tow mirrors. Non power fold
Just blinker in glass I now have the chrome Power Fold new style with rear cargo lights and parking lamp leds.
My truck was built in August 2014. I bought it last July and have been searching how to do this ever since . Every forum there is,been to dealers - no luck or not a straight answer. Have to have truck reflashed or not , this option won't work or that one etc.. That is until I came across this forum and PHIL. Phil took the time to do the research and has it down pat. I now have the mirrors I wanted with every option working as suppose to I got his harness and after several texts to determine what else I needed I had to get the GM RZY Harness. It was a pain but PHIL is there for you every step of the way. You pretty much in most cases have to upgrade your harness anyway so why not get PHILS'S. I'll tell you why cause all this re harnessing is a pain but having Phil as a go to guy to answer any question or problem that comes up means everything. And the feeling of when your done and EVERYTHING works , well it's all worth it. No taking to dealer for re flash. All works Phil even sent diodes and detailed photos and instructions on how to make cargo lights come on in reverse. Simply put without PHil I would still be searching
And still wanting these mirrors. Thanks a bunch Phil.
