When it comes to adventure, your memories don’t start when you get to your destination, they start 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 Tesla 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.


Features of Tesla/BMW i3 Wiring Harness Include:

  • NO cutting or splicing the vehicle wiring
  • Isolates trailer light operation from tow vehicle's electrical system so if something were to happpen, then won't affect each other
  • Works with 2 or 3-wire systems
  • Rated for up to 4.2 amps for turn/stop, and 7.5 amps for taillight trailer circuits – plenty for towing with your Tesla
  • Integrated overload protection
