Replacement 7-Way Recommendation for 2003 Ford F-250

Question

Question:

I need a factory replacement trailer light plug with wiring harness for my 03 F250. I see you have some that are similar but the connectors and pin locations look a little different than what I have. The Ford part number on mine is XL3T-14A464-BB. Do you have something that will work? Thank You,

For your 2003 Ford F-250 we have replacement 7-ways like with the Curt # C55774 which plugs into the round connector at the back of your current 7-way but if you are looking for a harness further up the wiring we won't have a way to help with that.
