- Application: This vehicle-specific dual-output wiring extension is designed for select models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram, and Toyota trucks. It plugs into your truck's existing factory 7-pin connector, adding a secondary 7-way RV blade socket and a 4-way flat socket in the truck bed for maximum towing flexibility. Please note: installation requires a factory-provided cutout in the truck bed.
- OE Part Number: [This is a vehicle-specific extension harness designed to work with your truck's OEM wiring. Please verify compatibility with your specific truck year and model.]
- Sturdy Structure: Engineered for durability, this extension features a heavy-duty, molded black plastic housing with a spring-loaded dust cover to shield the connection points from debris, moisture, and impact. The robust construction ensures a stable, long-lasting electrical connection in demanding truck bed environments.
- Enhanced Driving Experience: This plug-and-play system eliminates the need for wire cutting or splicing, offering a convenient solution for 5th wheel, gooseneck, or standard trailer connections. By providing both 7-pin and 4-pin outputs in the truck bed, it retains full use of the rear bumper socket and streamlines trailer hookup, significantly improving towing versatility and efficiency.
- Customer Service Commitment: We are confident in the quality and fit of our vehicle-specific design. For the easiest possible installation, please ensure your truck bed has the necessary factory cutout. Our customer support team is ready to assist with any compatibility questions to ensure a successful upgrade to your towing setup.
