Trailer Wiring Connectors

By Valley Industries®

Trailers are required to have at least running lights, turn signals and brake lights. To provide the power and a hook-up for these, the tow vehicle's wires are tapped into. This is accomplished through either a T-One connector (if available for your vehicle) or through hardwiring. The T-One Connector is pre-wired to a 4-pole flat that can adapt to a 6 or 7 way round connector. Hardwiring requires the installer to locate the proper wires in the tow vehicle.

4-Way connectors are available allowing the basic hookup of the three lighting functions (running, turn, and brake) plus one pin is provided for a ground wire. 5-Way connectors are available allowing the basic hookup of the three lighting functions (running, turn, and brake) and besides the ground, one pin is available to provide support for another function. Usually the 5-Way Flat is used for trailers with surge brakes. The additional wire is tapped into the backup lights to disengage the trailer's brakes when the vehicle is reversing.

For 7-Way connectors, the three main lighting functions, additional pins for auxiliary power, trailer battery charging etc. are available.
