7-Way Round Pin to 4-Way Flat Plug Adapter

Effortlessly join your socket and molded connectors with a trailer plug adapter. This one-piece molded trailer connector adapter allows you to convert a 7-way round pin-style trailer socket into a 4-way flat molded trailer connector. The 7-way round pin socket is most common in RVs, caravans, and large trailers. The 4-way plug will have a ground wire and three wires to control the left turn, right turn, and tail lights. The 7 pin to 4 pin trailer adapter will allow you to use a smaller trailer that typically has the 4-way plug with your larger trailer socket. Simply insert the adapter into the socket, and then plug in the molded connector. This item is manufactured to interchange with a standard 4-way flat trailer molded connector. It is made from a nylon material for added corrosion resistance.

  • Innovatively designed one-piece molded 7 pin to 4 pin trailer adapter.
