This US-made trailer wiring kit powers the lights on a trailer while protecting your bike's wiring system and, on newer bikes, the engine control module. This kit can be used on bikes that don't have a plug-and-play kit available and do not require a CAN-BUS decoder module including BMW, Honda, Yamaha, Suzuki and Kawasaki. (On these bikes, CAN-BUS may be used but it does not need to be decoded for signaling circuits.)

This kit is available for trailers set up with 4-wire or 5-wire lighting systems. If you aren't sure which you need, check out this video that explains the differences between the two systems.

Wiring harness for motorcycle

Dean Gaumont on May 29th 2022

Really pleased with this product, good instructions and diagram, was able to install myself, had one question which was answered promptly by Dale. Great company with excellent customer service and top quality products. I am now able to enjoy my motorcycle with many more options now that I can pull a trailer or camper.

Installed was easy on my 2004 Yamaha Royal Star Venture with the included directions and how to video on the website. It didn't hurt that the demo bike on the video was the same modle as mine. Harness is of good quality and works as it should. This is the my first time purchasing from Open Road Outfitters, shipping was fast and will use them again in the future.

This is the second bike I have install this on. It is intimidating at first glance, but if you read thru the instructions and watch his video its pretty straight forward. Both times i got it correct the first time! and I am an electrical idiot!

Quick and easy to install on BMW K1600. Much smaller than other isolators making for a neat installation in the limited space available on the K1600 under the seat.
