Installed the hitch and wiring today. Hitch was pretty easy, just had to bend the access holes in the frame rail just a hair bigger. Probably a 30 minute job.
Wiring less easy. Didn't like how much I had to cut the grommet to snake the wiring out to the headlight after doing the first and using a ton of RTV to seal it up. For the second side I cut the wiring kit wire and pushed that through a tiny hole then soldered it back together Wish I'd done that on the first side. 2018's at least have a grommet in a perfect spot to snake the trailer wire out but same issue so I have a replacement grommet on order and will do the same there for a clean install. For power, I grabbed power from the rear 12V power port which has a dedicated 20A fuse and this requires just a 10A supply. The only "gotcha" is that it only has power with the key on so the brake lights turn signals only work with the key on. That would also be true of the hazard lights. I don't see that being an issue.
