Adding additional trailer wiring allows you to outfit your vehicle with a standard connector for plugging in your trailer wiring for towing. Each T-Connector is vehicle specific and plugs into existing wiring without any splicing required. Ensure your wiring harness does not drag on the ground by visiting our Eclipse trailer wiring bracket.

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 Toyota 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.
