The JMK-IIT INC 16977 is a 4-Way Flat Trailer Wiring Harness Kit designed to provide electrical connection between a towing vehicle and a trailer. This kit typically includes a 25-foot color-coded harness for the trailer side and a 4-foot connector for the car side, ensuring proper transfer of tail lights, brake lights, and turn signals. It features 18 American Wire Gauge (AWG) conductors made from pure copper wire with tin plating for optimal conductivity and corrosion resistance. The wires are protected by a premium PVC coating for durability and are color-coded for simplified installation. The harness complies with SAE J1128 standards, indicating it meets specifications for low-tension primary cable used in automotive applications, with resistance to heat, vibration, and fluid exposure. The bonded, wishbone-style design helps in easy routing along the trailer frame and reduces tangling. Essential installation accessories such as screws, washers, wire nuts, metal clips, and a 3-way splice connector are included to facilitate a complete and secure setup.
