I also just purchased a 2022 F350 and am going through the various set-ups. I spend a day last week pulling the wiring harnesses through my 35ft 5er. Most of that time was dealing with the 4ft from the pin-box to the basement (between exterior sheeting and styrofoam insulation). What a pain pulling the large connectors through!
I just tie-wrapped the yaw sensor cable to the umbilical (along with the other harness also) and mounted the yaw sensor on the pin box. That's the easy one.
The other harness I pulled through the front as mentioned, and then ran along the basement ceiling as far as the tpms sensor would go, wish the cable was 5ft longer. Ended up mid-basement in front of the wheels, I tie-wrapped this to the down toilet pipe.
The backup camera is mounted at the top of the rear wall. It's cable comes through the basement with the tpms sensor cable and then up the vent stack onto the roof, it runs on top of the roof to the back.
Tires are all off of the 5er now awaiting transmitter mounting in the next day or two. Then I'll be able to check out how well the various sensors are functioning in my implementation. I'll let you know. Good luck with yours!
