MCS Harness & Switch Kits

21 products — part of all Harness & Switch Kits

MCS harness and switch kits simplify electrical installation on Harley-Davidson custom builds, rewires and accessory fitment projects. Pre-wired harnesses eliminate the need to splice and terminate individual circuits, reducing the risk of connection failures, short circuits and the intermittent faults that can be difficult to trace once a bike is fully assembled. MCS provide harness kits and switch housings to cover a range of Harley-Davidson applications — from full loom replacements on bobber and chopper projects to partial harnesses for adding lights, indicators or accessory circuits to an existing system. Quality electrical components matter on Harley-Davidson: vibration and moisture find every weak connection, so using properly rated harnesses and switches with good crimp and seal specifications is essential for long-term reliability. Iron City Motorcycles, Leeds' authorised Harley-Davidson dealer, stocks MCS electrical components as part of a comprehensive wiring and controls inventory.
