A must-have for trailers with a 5 wire system; separates the combined CAN-bus signal allowing it to correctly operate lights on trailers
Features new wiring that combines brake and turn signal functions together on a single wire from a computer module to lights
A plug-in connection between sub-harness PART #3902-0165 (sold separately) and the trailer wiring isolator
For use ONLY with RIVCO Universal Trailer Wiring Isolator PART #3902-0119 (sold separately)
NOTE: 2014 models come equipped with a new CAN-bus style wiring and require the use of isolator PART #3902-0119.
This will draw all power for trailer lights directly from battery and not adversely affect CAN-bus system.
