The Genuine Toyota trailer wire harness provides a 4-pin connector located on the trailer hitch to provide power to your trailer's brake lights, turn signals and taillights. Featuring a converter assembly, fusing, cables and connectors all specifically designed to work with your existing electrical system – you can count on durable and reliable performance, as well as simple and convenient installation.
Before towing, confirm your vehicle and trailer are compatible, hooked up and loaded properly and that you have any necessary additional equipment. Do not exceed any Weight Ratings and follow all instructions in your Owner's Manual. The maximum you can tow depends on the total weight of any cargo, occupants and available equipment.
