Mission complete! The passenger side is a piece of cake, the signal stalk is relatively simple, but oh man, that driver side fog light assembly is hard to get to (that screw that is furthest away is obstructed). Didn’t get it fully tight, but tight enough on the drivers side. The dealer wanted $850 for an aftermarket unit with a button that goes on the dash. I’m not sure if they are just trying to get one over me or they truly do not know that the vehicle is pre-wired for this.
Next project is figuring out if the front parking sonar is just as straight forward.. buy an XLE model lower bumper/grille, install it, and plug in to the harness that’s on the passenger side near the fog light as empty. The only question I have is whether or not it will be automatically added to the settings menu?
