Found a box with an F150 / 250 trailer wiring harness. In box with instructions. Part # F65B 15A416AA Has 6 pin grey plug on one end (instructions say it plugs under the dash) and wires as follows: Blk- illumination feed, Wht-ground, Red-battery feed, Grn-stop lamp, Blu-trailer elec brakes. Mystery is year of vehicle. If anyone knows any details or wants it, lemme know. I'll create a buy now item number.
what you have is the wiring adaptor that lets you hook into the factory harness, so you can hook up trailer lights and brakes. not sure what year it fits. hope this helps
yeah, its a harness for a trailer. These usually just plug into the rear light/directional system and run from a hole you drill in the bumper. Check out the female end of the trailer before you install there are many different conectors. Unless you are good at electrical work I would not try to put it in yourself. Modifications may be needed to fit trailer. The trailer brake you will have to run into the cab. Have fun TJ
