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.

I was impressed with the ease of install. the videos were also very helpful. It was worth every penny knowing that i had the exact parts i needed and was able to do the work myself knowing it was going to work when i was done.
As advertised, installation video was perfect, it was a lo harder to install than I expected
Boost auto rzy harness was perfect for my 2014 gmc 1500 slt tow mirror upgrade; their video instructions make it a walk in the park. Great to have such a good company to buy from. A++ Thank you.
Good experience, easy to use website, and fast shipping
Install was easy only problem I had was reaching inside the frame to get the door harness, but that’s not boost autos fault Definitely recommend!
