About this product
Upgrade your custom motorcycle's electrical system with the Thundermax Electronic Harness Controller. This compact and versatile unit simplifies wiring and enhances functionality, ensuring reliable performance in any environment.
Description
The Thundermax Electronic Harness Controller streamlines your motorcycle's wiring system by consolidating multiple functions into a single, easy-to-install package. It allows a dual-filament bulb to function as a tail light, brake light, and turn signal, eliminating the need for a separate center brake light. The included ribbon cable makes it easy to integrate generic indicator lights, providing a clean and customized look. This controller performs all fuse, relay, and signal-canceling functions, reducing complexity and improving reliability. Weather-resistant connections ensure trouble-free operation even in the most challenging conditions. Its trim-to-fit harnesses make installation a breeze on nearly any custom bike, and its compact design allows for easy concealment.
