Question:
I bought a curt custom wiring harness part 56000 so I could wire an in bed plug for my gooseneck and also retain the bumper plug. Site said it would fit my 2000 f350. All plugs on the curt are round. Factory trailer plug on truck is square. Am I missing something? Do I need an adapter, or is this the wrong part. Thanks in advance.

Hey Jon! You'd want to install # C55243 which plugs into your factory rectangular plug, then plugs into your 7 way. Then you can install the part you already bought, the # C56000, which goes behind the 7 way round and runs up to your bed for the 5th wheel to plug into.
What kind of trailer do you have, Jon?
