Electrical Adapter - 7 Way Round Vehicle to 4 Way Flat TrailerThere are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system. Some trailers only need the bare essentials—running lights, brake lights, and turn signals—while others require a connection for reverse lights, electric brakes, and auxiliary power. With connectors ranging from simple to complex, it may be the case that the connection between a vehicle and the trailer is not a perfect match. For example, a truck may be equipped with a 6-way round socket, but the trailer may have a 4-way flat plug.For this very common problem, CURT offers a quick and simple solution in the form of an electrical adapter. An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and a vehicle socket. It easily plugs into a vehicle's electrical socket and usually requires no additional wiring. CURT offers an array of adapters to accommodate most types of plugs and sockets, including 4-way flat, 4-way round, 5-way flat, 6-way round, 7-way RV blades, and more. This electrical adapter is designed to adapt a 7-way round vehicle socket to fit a 4-way flat trailer plug.
