This kit adds the wires required for adding towing mirrors to the cabin for 2014 & early 2015 Silverado & Sierra trucks. This kit, when combined with our modify door harness will get ALL of the lighting features working properly on towing mirrors.
This upgrade will work for OEM mirrors (RPO code DQS or DPN) and any aftermarket mirrors that properly wire all of the wires into the OEM style connector.

Watched the video before and during install, and it made it super easy. I am super picky about how I am about stuff like that making it nice and neat, so I’d say install took about 6 hours give or take with distractions.
