Phil knows what the hell he’s talking about. I have a ‘14 so I also had to install the RZY harness. I got my mirrors from 1A and with Phil’s harness everything went really well and I only had to ask him a few questions and also remind myself that their is an end to this madness. I have a fully functional set of power fold tow mirrors on my truck now and they work like a dream as my family and I are traveling with a 30’ travel trailer behind us. They were a necessity and I am grateful for his quick reaction to my questions about the RZY harness. Couldn’t have done it without him. We started in South Texas and went to the ozark mountains (Arkansas) and are now in NC at the great smoky Mountains. Sent from my iPhone using Tapatalk
