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.

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.
