Trailer cable line set
This trailer wire extension with a 4-way flat plug connector is designed to supply power for tail lights, turn and brake lights, as well as a ground connection. The white grounding wire is so enough long to wire. The trailer side ground wire is about 4ft. The trailer wiring harness features a ground wire. The white ground wire is made of 18-gauge, which is a corrosion-resistant terminal.
You can install the trailer wire so quickly and easily through the 4-way connectors. 4-pin connectors are available allowing the basic hookup of the three lighting functions (running, turn, and brake lights) plus one pin is provided for a ground wire. Most standard light duty trailers will use a 4-pole flat connector. Not compatible with motorcycle trailer wiring, and you could confirm the fitment to be not the wrong item before ordering.
