I swapped out my stock power folding mirrors with power folding tow mirrors from 1A. The mirrors have the power extend built in, but my truck did not have that option. I'd like to add it. I'm pretty good at wiring etc, but didn't know if anybody had done a write up on it. I tried to do a search, but admitedly that part I'm not real good at. I know I'm not the first one to have this problem. I found a video on youtube that gave links for the parts he used, to add power extend, but he had a shop do the wiring so there was no help there. I'm not sure on the wiring part. Truck is a 2014 Lariat. Thanks for any help.
