The CURT 56601 7-Way RV Blade Replacement Harness is a professional-grade, heavy-duty electrical cable engineered to restore a reliable electrical connection between your towing vehicle and trailer. Designed specifically for the trailer side of the connection, this 6-foot-long male-ended harness features a standard 7-way RV blade plug. It serves as a direct, drop-in replacement for worn-out, corroded, or damaged trailer plugs on RV travel trailers, utility trailers, goosenecks, horse trailers, and 5th wheels, keeping your power flowing smoothly and ensuring road safety.
This premium harness is designed with a heavy-duty, weather-resistant black PVC outer sleeve that shields the internal copper wires from rain, dirt, road salt, and UV damage. Inside, it features high-quality, multi-gauge color-coded wires (comprising 10 AWG, 12 AWG, and 14 AWG lines) that handle everything from basic taillights, turn signals, and brake lights, to high-demand circuits like electric trailer brakes, backup reverse lights, and auxiliary 12V battery charging. The color-coded design makes splicing into your trailer's existing junction box or wiring system simple and error-free.
Heavy-Duty Multi-Gauge Wiring: Equipped with high-conductivity copper wires, including 10 AWG main power/ground lines and 12/14 AWG auxiliary lines to handle high-amperage towing accessories.
Tough Weatherproof Shielding: Protected by an AWM 2586 heavy-duty insulated outer jacket rated for up to 105°C (221°F) and 600V to withstand extreme road environments.
Standard 7-Way RV Blade Plug: Male-end connector head features solid brass terminals and a molded-in finger pull grip for easy plug-in and disconnect.
6-Foot Generous Length: Provides plenty of slack to comfortably route from your trailer's tongue to your truck's bumper receptacle, preventing binding during tight turns.
Color-Coded Splicing: Follows standard trailer wiring color codes, making it simple to trace, splice, and wire into your current trailer electrical system.
