This video details the install of Boost Auto wiring kit part number 1846 which adds the missing wires to your GM door harness for upgrading from small mirrors to towing mirrors. This gets ALL of the circuits including power folding to properly function so the mirrors can work plug and play without running additional wires into the cab. The lighting circuits include cargo , running light (park light), and turn signal. Please reference our website for getting the front light to work as a running light and signal, or the side light to work as reverse.

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), Boost Auto Parts mirrors (if the plug and play option is selected), and any aftermarket mirrors that properly wire all of the wires into the OEM style connector.
