Recommended Wiring for 2003 Ford F-250 for 7-way and 4-way Trailer Connection
Question:
Do you have wiring harness that plugs into2003 f250 superduty and seven way with bracket an flat four
asked by: James
Expert Reply:
For your 2003 Ford F-250 Super Duty, we have the combined 7-way and 4-way option with the bracket available. If you have the factory 7-way plug, then we have the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End # HM40975 that connects to your factory round connector. We also have the Curt # C55774 or Reese # 74682 if you prefer that style.
If you don't have any factory wiring, then you need to start with a 4 flat, like # 18252. Once you have a 4-way, you can then use the kit # ETBC7 to upgrade to a 7-way and 4-way with all the wiring functions. If you have the factory 4-way then you can use # 37185 to complete the wiring with the 12v and Brake controller wiring found in the rear frame rail.
You will still need to add a brake controller like # 90195 and wiring harness like # 3035-P for factory 4 way or factory 7-way to fully work. The # ETBC7 kit will be needed if you have no factory wiring for the brake controller.
