I located the temp sensor behind the grille. No power fold or extend. The only upgrade on these new mirrors are the amber clearance lights on the front and the Rear facing cargo/ reverse light. Just need to figure out how to tie them into the BCM or existing circuits.

There is a lot of information in this post that has helped me understand many of the complexities of upgrading mirrors. I have an early 2015 2500HD Diesel that has tow mirrors with heat, power, and signal in the glass. I bought New style aftermarket Mirrors with the same features plus clearance lights and backup/courtesy light. No power fold or extend. Since the temp sensor is still behind the grille, I don’t have to worry about the the K40 sensor but I would like the marker lights and courtesy lights to work. Can this be done without any major complications or modifications? I should mention the truck also has seat memory option as this seems to cause issues. Any help would be greatly appreciated.
