Universal Trailer Wiring Isolator – TWC003
When connecting trailer lighting to a motorcycle using an isolator is required to prevent error codes at the gauges as well as damage to your factory motorcycle electronics and wiring. Also many times it is necessary to convert the motorcycles 4 or 5 wire tail light system to the opposite on the trailer being towed.
RIVCO designed the TWC003 combination isolator and convertor to be plug-n-play with RIVCO sub-harnesses. It features a selector button with corresponding colored LEDs to change the input and output functions. The TWC003 has a 36” wire loom and a “5 flat” trailer plug which also mates with all “4 flat” connectors molded to the wires.
Installing the TWC003 is easy when you follow the included wiring diagrams and instructions. The small 3” x 1” x 1” size of the TWC003 isolator make it easy to mount in an out-of-sight location like under the seat. The TWC003 is a universal isolator; meaning it works on most motorcycles.
