i am adding lighted tow mirrors on my W/T truck and wanted to ask ideas for running the wires from other people that have done it as the plug pin hole on the cab side looks small all ideas greatly appreciated

Best way is to either modify your door harnesses and add the missing circuits or purchase my custom door harnesses.

Since you have a 2015, you’ll want to do some exploring and see if your truck has the pins delivered to the door jamb circuit. All 2014 trucks and early 2015 trucks will have the tow mirror light circuits missing on the door jamb connector. If this is your case, there will be a need to run an additional GM harness inside the cabin and under the hood.

See pic to see what you’re looking. Specifically, pins 9 and 11.
