Question:
2015 ford f-350 regular cab and chassis with utility bed but doesn’t have a trailer harness that I can find. I put a receiver hitch on and needing a trailer plug. Do they make a trailer harness that will plug into factory wiring harness?

Hey Ryan, if you want to find an OEM style harness that would provide a 7-way for your 2015 Ford F-350 cab and chassis you'd need to check with a Ford dealer. We can help but it would be with a setup that gets hardwired in like with the part # C58044 and then convert to a 7-way you'd need an adapter like the part # 37185.

You will need the T harness adapter from Ford, if you want the trailer battery charge circuit to work you will also need a relay and fuse for the battery junction box, and a trailer brake controller kit either from ford or aftermarket.
