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 7-way RV blade vehicle socket to fit a 4-way flat trailer plug. It is constructed from quality plastic and requires no splicing. All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence.

  • VERSATILE DESIGN. This trailer wiring adapter makes it easy to connect a mismatched vehicle socket and trailer plug, adapting your 7-way RV blade socket connector on your vehicle into a standard 4-way flat
  • USEFUL EXTENSION. This trailer hitch wiring adapter comes with an 8-foot coiled harness to provide plenty of extra length to accommodate a variety of towing setups. The coiled cable also helps keep the wiring harness from scraping on the ground
  • EASY GRIP. Plugging in your trailer wiring and trailer lights is easy with the ergonomic design of this trailer wiring adapter. It features tabs on the sides for a better grip when plugging into the vehicle or unplugging
  • NO-SPLICE INSTALL. This 7-pin to 4-pin trailer adapter wiring comes ready to plug into your vehicle or trailer wiring with zero splicing required. It can be used to connect the taillights, brake lights and turn signals
  • DURABLE CONSTRUCTION. For long-lasting use and a reliable connection, the housing of this trailer harness adapter is made from durable black plastic that will never rust or corrode
