OEM Style 7-Way Replacement for 2003 Ford F-150

Question:

I am looking for a 2003 ford f150 trailer wiring harness part number YL3Z-13A576-GB which I think is obsolete. Do you have anything that will match up with this harness? Thanks.

Hey Chas, so we do have a similar solution to what you are looking for that provides a 7-way for your 2003 Ford F-150 with the Curt part # C55242. This would definitely work for you and is currently available.

@JeffreyE Are you referring to the harness YL3Z-13A576-GB that Chas asked about or the Curt?

@JeffreyE I don't have a way to look that up. A Ford dealer could help with that or if you had a circuit tester like the # PTW2993 you could test the wires for voltage when different taillight functions are applied.
