well another issue i have is this truck, no park(running lights) on the trailer plug.. i cut the brown wire about 3 inchs from the factory plug (truck side) and have no power.... replaced the fuse and swapped the relay out with another and still no power for the running lights on the trailer.everything else works fine ie turn/brake/elec brakes/battery charge

any ideas?

found it, about 2 ft up the harness someone spliced in a new plug and the park light wire was broken
