4-Way Connectors

4-Way Connectors

Commonly used for small boat trailers, utility trailers, popup campers and others that don't have trailer brakes, 4-way wiring connectors use four wires to carry out essential lighting functions, including turn signals, brake lights and taillights. These connectors can be spliced into existing wiring as a replacement on your vehicle or trailer.
