GM Modify Door Harness for Plug and Play Tow Mirrors - Silverado & Sierra (2014-2019)

$ 49.95

Sold as a set (kit covers both sides). This wiring kit adds the missing wires to your GM door harness for upgrading from small mirrors to towing mirrors. This gets ALL of the lighting features working properly on towing mirrors. This kit is all that is required for 2015.5-2019 trucks. Why spend $200+ on replacing your door harnesses when you can just add the missing wires for a fraction of the price?

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.

Got this harness to get all the functions after switching to tow mirrors. With a step by step from boost auto DIY videos online, i think this kit was totally worth the money. Thank you guys for the customer service(got an email response same day to a question i submitted on a sunday) as well as the kit itself.

Great product, fantastic customer support!

Super easy to use. Just followed the video on YouTube and I was able to get plug and play results without having to reflash the BCM. Installed on a 2015.5 GMC Sierra 2500HD 6.6L diesel; with Boost tow mirrors.
