Universal plug-and-play adapter that connects a 6-way round vehicle socket to a 7-way RV blade trailer plug, with the 6-way center pin designated for taillights.
The Curt 57667 provides a simple solution when your tow vehicle has a 6-way round socket but your trailer is equipped with a 7-way RV blade plug. It plugs directly into the existing vehicle socket and accepts the trailer's 7-way plug without requiring cutting or splicing.
This adapter supports trailer taillights, brake lights, turn signals, reverse lights, electric trailer brakes, and auxiliary power. The 6-way round side uses the center pin for the taillight circuit, so the vehicle wiring configuration should be verified before use.
