I'm in need of a little help. I have a 2004 FX4 5.4, when I plug a trailer into the factory wiring harness i get every thing but the running light. I can plug into my 2015 F250 all lights work as should. a friend said there are fuses for these lite.
i bought this truck years ago (trailer lights use to work) and dont have the owners manual for the fuse panels layout does anyone Know if there is a fuse for the trailer running/ marker lights. and what is the Fuse number.
thanks for any help, hate to take the truck in for "just a fuse"
thanks
