CURT 57040 Trailer Wiring Adapter, 7-Way Round Vehicle Socket to 4-Way Flat Trailer Plug, Plug and Play Electrical Adapter, No Splice, Black Plastic

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 round 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 connects a mismatched vehicle socket and trailer plug by adapting a 7-way round vehicle-side socket to a standard 4-way flat trailer-side plug.
• EASY GRIP — Plugging in your trailer wiring and trailer lights is easy with the ergonomic adapter design, featuring side tabs for a better grip when plugging into the vehicle or unplugging after towing.
• STANDARD CONNECTION — This 7-way round to 4-way flat adapter connects trailer tail lights, brake lights and turn signals; 4-way flat output does not support electric trailer brakes, reverse lights or 12V auxiliary power.
• NO-SPLICE INSTALL — This plug-and-play trailer wiring adapter requires no cutting or splicing; verify your vehicle has a 7-way round socket, not a 7-way RV blade socket, before ordering.
• DURABLE CONSTRUCTION — For long-lasting use and a reliable connection, this trailer harness adapter uses a durable black plastic housing that will not rust or corrode.
