I spoke with my contact at B&W regarding the Custom Headache Rack # BWPUCP7500BA referenced in your question. He stated that on your 2017 Ford F-350, you will just need to wire the pigtail into the actual truck light wires on the vehicle, as going to the 7-Way on the 2017 disable the rear sensors as you mentioned. Wiring directly to the truck light wires will allow the truck to operate as normal and it will not act as if there is a trailer connected.

If that connector you are plugging into is related to the tow package wiring, then that is what is causing the problem on your 2018 Ford F-250.

I recommend inspecting all of the ground locations as well as the ground wires coming from each of the lights. Look for loose connections or pinched wires.
If your lights use the plug-in style pigtail harnesses (see photo), look... view full answer...

Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces.
The light grounds should also... view full answer...
