4 Flat Trailer Wire is a cable designed for the electrical connection between the trailer and tow vehicle. With a flat four-wire configuration, it simplifies the connection of the trailer electrical system. The four wires transmit brake light, tail light, and turn signal signals, as well as provide grounding to keep trailer lighting and signaling in sync with the towing vehicle. It is widely used in a variety of small to medium-sized trailers such as boat trailers, ATVs trailers, and camper trailers.
