There 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 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 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 4-way flat vehicle socket to fit into a 1-1/4" license plate light hole, providing a convenient attachment point for your trailer wiring plug. It features quality plastic construction, requires no splicing and comes with a dust cover, protecting the socket from dirt, water and road grime. All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence.

  • NO-SPLICE INSTALL. This 7-pin trailer adapter wiring comes ready to plug into your vehicle or trailer wiring with zero splicing required
  • DURABLE CONSTRUCTION. For long-lasting use and a reliable connection, the housing of this vehicle-side 4-pin trailer wiring plug is made from durable black molded rubber that will never rust or corrode
  • STANDARD CONNECTION. This trailer hitch wiring adapter plugs into any standard 4-way flat and can be used to connect the taillights, brake lights and turn signals
  • DUST COVER. To promote long-lasting use and weather resistance, this 4-pin trailer wiring harness comes with an integrated rubber dust cover. It easily fits onto the 4-way flat connector when not in use, protecting it against the outdoor elements
