Trailer Wiring Kit: Harley 2014+


SKU: H14.5 Categories: ,


A relay-isolation harness is a good investment if you’re planning to pull a trailer. This setup allows you to drive a set of trailer lights (standard bulbs or LEDs) without affecting or loading the bike’s signal circuits.

In the event that a short develops in the trailer wiring (typically in the plug area), an inline fuse in the relay package protects both the bike and trailer. Your bike’s lights will remain unaffected and continue to work.

This kit is designed to work with Harley FLH/FLT touring bikes from 2014 to present as well as the Tri Glide from 2014 to present. It contains three components: a plug-and-play sub-harness that connects to the bike’s wiring (no cutting required), an isolator and a 4-to-5 converter.
