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 version fits the Softail from 1997 to 2017.

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.

This is easy to wire. Directions are good. Mostly plug n play. Hardware comes with the connections that aren’t plug in. A little more $$$ then others, but a more trusted seller. Thanks Dale & company!
