7WAY RV TO 6WAY ROUND CENTER PIN AUXILIARY ADAPTER WITH TESTER

MIA's Description

The Curt 57255 is an electrical adapter designed to connect a 7-way RV blade vehicle socket to a 6-way round trailer plug. It facilitates the connection for tail, brake, turn signals, electric brakes, and auxiliary power. This adapter features a simple plug-and-play design that does not require cutting or splicing.

It includes an LED tester to confirm the proper function of the vehicle-side wiring connector and a dust cover to protect the socket from environmental elements when not in use. The center pin is designated for auxiliary power.
