Replacement 7-Way Trailer Connector for a 2003 Ford F-250 Super Duty
Updated 11/12/2021 | Published 03/04/2017
Question:
I have a 2003 F-250 SD 7.3L and it came stock with a 4 and 7pin combo however you can only unplug the 7 pin one and the 4 pin stays connected to the harness. The harness is around 18 inches long and plugs into the truck up by the frame and the spare tire. On that 18 inch long connector the plastic clips that hold the connectors together have both broken so neither side of the harness is secure. your part #118243 says only 1999-2001 but it appears like the gray rectangle connector is the same? unless the pins in it do not line up im not sure why this would not work? if this does not, do you have any items that will work? i do not need to replace the 4pin connector as i can get an adapter from 7-4 Hope to hear back from you. Thanks!

Ford Replacement OEM Tow Package Wiring Harness # 118243 is not confirmed to fit the 2003 Ford F-250 Super Duty. But what you could do is use # 40167 which is a fit. It is basically an in-bed 5th wheel/gooseneck 7-Way that Tees in with the factory trailer wiring. I have linked a video showing how it tees in.

Code 118423 does not show that it includes the 4 plug wiring on the side as my factory one has? Do you offer that? Thank you
