i had a similar problem on my 04 f150, but instead of it being the running it was the reverse lights not working. the fuse for my trailer reverse lights was the same as the trucks reverse light so maybe you can check the fuse for trucks running lights. if this dosent solve the problem most ford trucks have a relay some where in the line see if you can locate that and check there to see if there is power good luck

All the fuses I could find were good. Pulled the wire harness out of the truck back to a round plug and everything had continuity but when I reinstalled there was still no running lights. Spliced a wire from license plate light wire to running lights and now it works.
