There are several different types of connectors used to supply power from a tow vehicles electrical system to a trailers 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 your vehicle and your trailer is not a perfect match. For example, your truck may be equipped with a 6-way round socket, but your 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 vehicle socket. It easily plugs in your vehicles 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 6-way round vehicle socket to fit a 4-way flat trailer plug. It features quality plastic construction, requires no splicing and comes with an LED connector tester dust cover. Not only does this dust cover protect the socket from dirt, water and road grime, but it also allows you to test your vehicle-side wiring connector to ensure your electrical systems are functioning properly. All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence.
