Question:
I have a 2006 f350, I purchased this truck and someone previously hacked up the trailer plug. I’m looking for the OE or similar harness that go to the bumper to plug into a 7way/ 4flat receptacle. I will be adding a gooseneck hitch and T harness for that plug in the future so I was wanting to just find a OE type harness for the bumper

Hey Hunter congrats on your new truck. You can replace the connector on your F-350's bumper with the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package item # C55774. This one includes both a 7-Way and 4-Way flat. If you're needing any factory wiring behind this connector you'll need to go to an auto parts store because we do not sell factory replacement harnesses.
As far as a in bed 7-Way goes, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C56070. This harness puts a 7-way connector in the bed of your F-350 and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel or gooseneck trailer easier and more convenient.
