This video details the install of Boost Auto wiring kit which adds the missing wires to your GM door harness for upgrading from DL8 small mirrors to DL3 power fold small 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 turn signal and puddle light.

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 DL3) and any aftermarket mirrors that properly wire all of the wires into the OEM style connector.
