Compact trailer wiring adapter connects a 4-way flat trailer plug to a vehicle equipped with a 7-way RV blade socket. Plug-and-play design requires no cutting, splicing, or additional wiring.
The Curt 57241 provides a quick solution when the tow vehicle has a standard 7-way RV blade socket but the trailer uses a 4-way flat plug. Simply plug the adapter into the vehicle's 7-way socket and connect the trailer's 4-flat plug to the opposite end.
The 4-way output carries the basic lighting functions required by many utility trailers, boat trailers, and other light-duty trailers, including tail lights, brake lights, and turn signals. Its compact plastic housing features side grip tabs for easier installation and removal.

This adapter converts the connection type but does not add trailer brake, reverse-light, or auxiliary-power circuits to the 4-way flat connection. The 4-flat output provides tail lights, brake lights, turn signals, and ground only.
