Please Help... wiring issue

Thought I’d ask here first before I call the dealer. I have a 2017 F250 with only 4,000km, I’ve hooked up to three of my trailers and all of the lights work (signals, turns and brake) except the running lights!!?? Never had an issue with the trailers before, must be the truck.....any ideas????

There are a few threads on here about this same issue. I believe PIN number 7 is the issue. Maybe. Try the search. It was just discussed a couple weeks ago.

Also, did you check fuses?

The under hood fuse box lists:
65 - trailer tow lighting module
72 - trailer tow left hand/right hand stop/turn
84 - trailer back up lights
99 - trailer tow parking lamps
