6-Way Connectors
CURT 6-way connectors are commonly found on gooseneck trailers but are also used on everything from utility trailers and boat trailers to campers and 5th wheels. In addition to the basic lighting functions of running lights, brake lights, turn signals and a ground wire, a 6-way connector provides one wire for trailer brakes and one wire for a battery connection.
