Hello,
ive got an 2014 GMC Sierra pretty sure they have the DL8 in them as the mirrors are power adjust, heated. No turns and no power folding. I bought aftermarket tow mirror, but I know I’ll need the aftermarket harness for the singals and lights to work. As of right now once plugged in till I can figure out what I’m gonna do for the turns and lights to work I only have power adjust and heated. Which is fine for now but I do want the turns and lighting to work. They mirrors are the new style so they have the power fold and power pull out(meaning they slide out threw power instead of manually pulling them out) just wondering before I figure out what I am doing, what is the route I’ll be going and rough cost on how much it’s all gonna be? Thanks in advance
