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.

FAQ
Yes! We offer a power-folding sport mirror similar to a DL3 mirror in a full gloss black finish. It was specifically designed for trucks upgrading to power folding that were originally manual fold.
Check it out by CLICKING HERE.
If you have a 2014 or newer 1500 truck or a 2015 or newer 2500/3500 truck and originally had mirrors only equipped with power adjust and defrost (DL8) this will work to get the mirrors with turn signal, puddle light, and power fold (DL3) operational.
Yes, if you have the correct power folding switch.
We offer the switch in the options above. We also offer the mirrors by CLICKING HERE.
Power adjust, defrost, turn signal, puddle light, and power fold (if you add the power folding switch).
You can check your glovebox RPO code sticker. If you have A45 you have memory. If you don't have A45 then you do NOT have memory.
The memory seat buttons are located next to the driver's door handle. You can look to see if you have buttons that say 1, 2, SET. If you have them, your truck is equipped with memory.
This is only relevant for 2015 vehicles. If your vehicle is anything other than 2015 you do not need to check to see if it is equipped with memory.
