Curt 57008 7' 7-Way RV Blade Truck Bed Wiring Extension for Select Ford Trucks

Add a convenient 7-way RV blade socket inside the truck bed for easier 5th wheel or gooseneck trailer connections. This 7' plug-and-play harness retains use of the factory rear bumper socket and requires no cutting or splicing of the vehicle wiring.

Why Choose the Curt 57008 Wiring Extension?

Curt 57008 adds a second 7-way RV blade connector inside the bed of select Ford pickups, putting the electrical connection close to a 5th wheel or gooseneck trailer coupler. The harness plugs into the vehicle's existing OEM trailer-wiring connection and continues power to the original rear bumper socket.

The 7' extension includes a right-angle plug for easier routing, protective slit loom around the wiring, and a spring-loaded dust cover on the bed-mounted socket. For aluminum truck beds, the included isolator hardware helps separate steel fasteners from the aluminum surface to reduce the risk of galvanic corrosion.

7-Way RV Blade
