GM Modify Door Harness for Plug and Play DL3 Small Power Folding Mirrors - Silverado & Sierra (2014-2019)
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.
