Nilight Dual Output 4-Way to 7-Way RV Blade Wiring Adapter with Mounting Bracket

Unlock towing versatility with Nilight

Nilight's Dual Output 4 Way Flat to 7 Way RV Blade Wiring Adapter is designed to bridge mismatched trailer plugs and vehicle sockets. By converting a common 4-pin flat system to a standard 7-way RV blade, it opens up trailer options without reworking your existing harness. The solution is built for real-road use, where weather, dirt, and vibration are a constant presence. The dual outputs provide flexibility to service multiple trailers that use different connectors, helping you stay prepared for weekend getaways, work trips, or family adventures.

Built for practical, road-ready reliability, this adapter lets you keep your vehicle’s original wiring intact while expanding towing compatibility. The design supports both 4-pin and 7-pin connections, so you can reuse your current wiring in tandem with a ready-made 7-way plug for a trailer that uses an RV blade connector. The result is a cleaner, more adaptable setup that emphasizes convenience and consistency on the road.
