7' Custom Wiring Extension Harness (Adds 4-Way, 7-Way RV Blade to Truck Bed)
These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your 5th wheel or gooseneck trailer.
This extension harness provides connection points for both 4-way flat and 7-way RV blade connectors, and it comes in a length of 7'. It is compatible with select models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram and Toyota.
