Hey Levi!
You're looking for the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 which tees in behind the factory 7-Way and gives you a way to add another 7-Way in your truck bed. This part is for standard truck beds, but if you have an aluminum bed (like on a Ford truck) you'll need the Kit # C57008 instead.
You pulling a gooseneck or a 5th wheel?
