Universal trailer wiring adapter for connecting a 6-way round trailer plug to a vehicle equipped with a 7-way RV blade socket. Center pin is configured for the trailer brake circuit.
The Curt 57660 provides a simple solution when the tow vehicle is equipped with a 7-way RV blade socket but the trailer uses a 6-way round plug. It plugs directly into the vehicle socket and accepts the trailer connector without cutting, splicing, or rewiring.
The 6-way round connection supports trailer taillights, brake lights, turn signals, electric trailer brakes, and auxiliary power. This version is specifically configured with the center pin assigned to the trailer brake circuit.
