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.

Austin P. United StatesGreat Product
Very impressed with this. The price made me a little hesitant just due to the fact the price seems a little high since it's just made of wires and pins. The Installation videos could not be any more thorough and detailed. Most installation video's are half-fast and sloppy.
