MCS brings its characteristic depth of inventory to the Wiring category for Harley-Davidson motorcycles, providing an extensive selection of replacement harnesses, leads and universal electrical cable for both repair work and custom builds. As a comprehensive aftermarket supplier stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, MCS wiring covers the breadth of Harley-Davidson platforms from classic models through to modern Touring and Softail machines. Their universal-fit cables and harness components are engineered to handle the voltage demands of Harley-Davidson charging and ignition systems, making them a practical choice for everything from a straightforward repair to a full custom chop rewire. Whether you are sorting an electrical fault on an older Evolution Big Twin, extending leads for a new handlebar setup or building a clean custom loom from scratch, MCS delivers the consistency and value that riders and workshops rely on.
