The Maddog Wiring Harness is a pre-assembled 12V DC relay-and-fuse loom for all Maddog auxiliary lights and most 12V motorcycles and scooters, ready for the Maddog Switch or Switch Pro. A 30A water-resistant relay and a replaceable inline blade fuse guard the electrical system against overloads and short circuits. Automotive-grade, heat-resistant wire and weather-protected quick-connect connectors handle light rain and dust. Cost-effective, quick and clean to fit, it skips cutting and splicing for a professional finish, suiting daily commuters and touring riders with low to mid-power lights, including Maddog upgrades on a budget. The loom has black braided sleeving. In the box: harness with relay and fuse, pre-fitted connectors and an installation guide.
