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 without power fold or turn signal (DL8) to small mirrors with power fold, turn signal, and puddle light. This gets the turn signal and puddle working, and when purchased in combination with the power folding switch the power fold can be gained as well.

    Easy Install

    Wiring kit worked as expected and was super easy to install following the instructions provided. DL3 mirrors work like factory now!

    Hi Daniel, This is a universal kit that is also used for towing mirror upgrades. The towing mirrors utilize an additional wire, but that feature is not present on the small mirrors so it is not used in this installation. Thanks, -The Boost Auto Team

    Dl8 to Dl3 wiring harness

    Came in fast. Video explaining it was very clear. I couldn’t get the puddle lights to work on my mirrors but other then that everting else worked great.

    Side Mirror Upgrade

    Very straightforward, helped me fix the terrible job a previous shop did in attempt to have my signals work and was also causing a hyper flash issue. Works like a charm and the hyper flash error is gone as well now!
