Check fuses and the wiring to the connector. Check the actual connections for corrosion and dirt.

Fuses seem all good. Wires and connections are in great shape.

Parking light fuse is what will cause no trailer running lights. It is fuse 99 for the 2017 F-250

You have to turn on light, take out of day time running lights on mine to get trailer running lights

I ran into this issue, replaced fuse 99 30amp, and turned automatic lights off. Trailer lights work fine now.
