Universal Compatibility & Versatile Towing:Dual-output design supports both 4-pin flat and 7-pin RV connectors, enabling seamless connections between mismatched vehicle sockets and trailer plugs.Converts a factory 4-pin socket into a combination 7-pin RV and 4-pin flat output, accommodating trailers with varying electrical needs (taillights, brakes, turn signals, reverse lights, and 12V auxiliary power). Ideal for towing multiple trailer types with one vehicle connector.

Excellent Material:Constructed from reinforced ABS plastic for rust resistance and long-lasting use. Features tin-plated copper terminals and pure copper wiring for superior conductivity. Includes weatherproof silicone-sealed sockets, dust covers, and a protective black wire loom to guard against corrosion, abrasion, and environmental damage.

Enhanced Safety & Protection:Spring-loaded and silicone-sealed covers keep terminals clean and moisture-free. Black oil-resistant conduit shields wiring from wear, while dust covers on both 4-pin and 7-pin outputs prevent debris buildup. Ensures reliable performance in harsh conditions.

Multi-Functional Wiring System:Additional leads for brake, reverse, and auxiliary power functions expand compatibility with trailers requiring extra circuits. Dual-output design allows simultaneous use of 4-pin flat and 7-pin RV connectors, eliminating the need for multiple adapters.

Hassle-Free Installation:Complete kit includes pre-assembled wiring, mounting brackets, screws, nuts and instructions for quick setup. Universal mounting hole design simplifies installation, and connectors snap securely into existing sockets without wobbling. No specialized tools required.
