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.

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
