CURT 7-Way RV Blade to 6-Way Round Trailer Wiring Adapter, Center-Pin Auxiliary Power, Molded Housing

The CURT 57260 converts a vehicle's 7-way RV blade socket into a 6-way round trailer plug with a center pin carrying auxiliary power, requiring no splices.

When tow vehicles and trailers use different connector styles, a simple adapter lets you transmit lights, brakes and auxiliary circuits without rewiring either plug. The CURT 57260 is a purpose-built electrical adapter that bridges a 7-way RV blade vehicle outlet to a 6-way round trailer plug, keeping the center pin available for auxiliary power. Its molded plastic housing and ergonomic tabs make it quick to connect and remove while resisting corrosion and weathering.

How does this adapter preserve trailer functions?

It maps the standard trailer circuits from the 7-pin blade on the tow vehicle to the corresponding 6-pin round terminals so taillights, turn signals, brakes and auxiliary power remain operational. No modification of the vehicle or trailer wiring is necessary.

• Pass-through of running lights, brake lights, and turn signals

What should I watch for when using this adapter?

Confirm that your tow vehicle uses a 7-way RV blade socket and that your trailer expects a 6-way round plug with a center auxiliary pin. While the adapter routes standard circuits, verify the trailer’s auxiliary device ratings before powering heavy accessories.

• Match vehicle 7-way blade to trailer 6-way round with center pin
• Check accessory current draw against vehicle auxiliary output limits
• Inspect contacts and housing for wear before long trips
• Store dry when not in use to prolong connector life
