I’ll try to be brief. 2003 F-350. Owned it for a few months now. Just realize it is not equipped with a trailer wiring connection at the bumper. Must never have been used to tow. I need help identifying what I need to purchase. I tried searching but there are many different harnesses and options that come up. Some look correct but they say only for 1999-2001. All I see under the bumper is a harness connector that has nothing plugged into it and I assume it is where I would plug something new into. It has 2 rows of four holes in the middle and then four pins I think, one on each corner. Also, will the brakes on my camper work if I don’t have a brake controller? If I need one how hard is that to install? Thanks for any guidance you can offer.
