Wiring Harness is the bundle of wires that connects all electrical parts, like lights, sensors and motors, to the battery and control module. We group wires in protective sleeves and clip them along the frame so they stay neat and safe from dirt, heat or sharp edges. If a wire breaks or shorts, an electrical part stops working or sparks fly – and that’s messy. We inspect harnesses for cuts, secure loose clips, and swap damaged sections. It’s like the nervous system for your machine, don’t ignore it.
