Curt 57020 Dual-Output Connector Plug, 12 V, Black

A curt connector provides a reliable connection for your trailer wiring, using an industry standard format, such as a four-way flat, six-way round or seven-way RV blade. They can be used to-install new wiring on a vehicle or trailer or as replacement connectors for existing wiring. This particular connector is designed to be a ideal OEM replacement, providing a four-way flat socket and seven-way RV blade socket to accept either trailer plug type. It features a USCAR base to connect to any standard USCAR plug. Once plugged-into the USCAR socket, it provides a connection for the taillights, turn signals, brake lights, back-up or reverse lights, electric trailer brakes and a 12 V battery. It also provides a connection for the ground wire. This trailer wiring connector is built to withstand the elements. It is constructed from durable black molded plastic to be impervious to rust and it features spring-loaded dust caps to keep out rain, salt, grime and dirt when the connectors are not in use.
