Smart, Flexible T-Connectors for Heavy-Duty Towing

The CURT 56070 7ft wiring extension harness delivers a clean, reliable boost to your towing electrical setup. By adding a dedicated 7-way RV blade socket in the truck bed while preserving the factory rear socket, this harness creates a simple, ready-to-use pathway for 5th wheel or gooseneck wiring. The plug-and-play design removes the usual cutting or splicing steps, helping you align your truck’s electrical system with your trailer’s needs when you shift between trailer types or trips.

Designed for drivers who regularly switch between receiver hitches and specialized trailers, this extension harness keeps your wires organized and accessible. The 7-foot length provides flexibility to route the new socket through the bed without crimping or tension, helping you maintain a tidy, professional setup that’s ready for the road.

What to expect

• 7 ft custom wiring extension harness (adds 7-Way RV blade to truck bed, packaged)
• Routes a 7-way RV blade socket into truck bed while retaining use of rear socket
• Simple plug-and-play design eliminates the need for cutting or splicing

Real-world scenarios

Picture a weekend tow, where you need a bed-mounted power outlet to match a 5th wheel or gooseneck setup, while the bumper socket remains active for other trailers or accessories. The extension’s length helps you reach the right wiring location without stressing cables, and routing through the bed keeps everything neatly tucked away from path of travel and road debris.
