I’m very interested. Thanks for being the Guinea pig.
Given my limited abilities, I crawled under to survey the situation. Installing the wiring harness will be a cinch with one potential issue. At least on my 2021, there appears to be very little space between the rear of the trailer hitch and the spare tire pan. I wonder whether there’s enough room to pass the cable (with the orange connector) into the rear of the hitch.
Did you encounter such a limited space?
