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 is required for 2019 2020 2021 2022 Silverado and Sierra 1500 trucks upgrading to towing mirrors.

This kit adds the running lights, turn signals, and cargo lights features for the towing mirrors. This kit is all that is required for 2020+ Silverado or Sierra 1500 trucks originally equipped with bed illumination. 2019 trucks also need the RZY harness (reference below FAQ for more details).

Why spend $200+ on replacing your door harnesses when you can just add the missing wires for a fraction of the price?
