Toyota Sienna Wiring Harness – WH428811

Life should be a daring adventure and that adventure doesn’t start when you get to your destination, it starts when you begin your journey. With this modulite, everything is provided that you need to connect your vehicle's electrical system to a trailer for towing to safely get you to your next destination. Rather than cutting and splicing into the wire, the wire harness has a clamp that goes around the wire to sense which functions you are using including turn signals, taillights and stop lights.

This Sienna trailer wiring modulite works with the factory wiring and isolates the trailer light operations from the tow vehicle’s operations. That means that if something were to happen electrically, the systems are separate, so it won’t affect or damage the other system.

• Simple plug-and-play design
• No need for cutting or splicing
• 4-way flat output connects tail lights, brake lights and turn signals
