The Micro Harness Controller Kit is designed to streamline your motorcycle's electrical system. It performs all fuse, relay, and signal-canceling functions in one compact unit. This kit provides multiple flasher combinations, allowing you to control signal canceling, hazard lights, running lights, and turn signals from a single dual-filament bulb.
Crafted from durable billet 6061 T-6 aluminum, the housing is both lightweight and robust. Its 7' trim-to-fit wiring design ensures a neat installation that can be easily hidden on custom motorcycles.
Utilizing relays to distribute power functions, this kit eliminates the need for running large wires to all switches, making installation simpler and cleaner. The weather-resistant connections ensure reliable operation even in extreme conditions.
Additionally, it is compatible with micro switches and is suitable for choppers and custom bikes with separate brake lights (except '04-'20 Big Dogs with proprietary hand controls).
