Replacement Trailer Wiring Harness for a 2003 Ford F-350

Question:

I am looking for the OEM wire harness that runs from the frame connector too the 7 way plug. I have purchased a used 2003 Ford F-350 and they have spliced a 7 pin Pollard in the truck, this birds nest of wiring is having poor connections. Can you help?

I do have options for you but we do not carry OEM replacement parts. The correct harness for you would depend on what type of connector you have on the frame rail. If you have a square connector then you are going to want to use the Hopkins Plug-In Simple Wiring Harness for Factory Tow Package part # HM40165 which is a direct plug and play option. In order to add a 7-way you are then going to want to use the Adapter 4-Pole to 7-Pole and 4-Pole part # 37185 which will give you both 4 and 7-way trailer connection points. You will need to splice into a few wires to install this connector.

If you have a round connector then you can use the Reese Multi-Plug Wiring Harness for Factory Tow Package part # 74682 which will also give you both 4 and 7-way trailer connections points but this option is completely plug and play. If none of these options are what you are looking for then please send me a photo of what you have so I can better assist you.
