Wiring Harnesses, Cables & Connectors
About Wiring Harnesses, Cables & Connectors
A wiring harness is the bundle of wires and plugs that carries power and signals around the bike, and a damaged one can cause lights, switches or accessories to fail. Riders replace a harness when wires are chafed or melted, or when a repair is not worth the time.
Every listing in this category is for a particular job. There are handlebar wire harnesses for Harley-Davidson Electra Glide Police, Road Glide Police and Road Glide Custom models, model wire harnesses for the Road King and Street Glide, a CAN bus wiring extension for the Road King Special, a USB port, and a universal connector kit. A handlebar harness carries signals from the switch housings to the rest of the bike. Year ranges in the titles matter, because plug types and wire counts change between years.
Brands here include LA Choppers, Koso North America and Rick's Motorsport Electric. The parent group is Electric Motorcycle & Scooter Parts. For a fit check before you order, read why parts don't fit and how to avoid it.
FAQs on wiring harnesses and connectors
What does a handlebar wire harness connect?
It carries signals from the handlebar switch housings and controls to the rest of the bike's wiring. Handlebar harnesses are listed for specific models and year ranges, so the plug and wire count must match your bike.
How do I know a harness will plug in?
Match the model and year in the title, then compare the connector shapes and the number of pins with your old harness before you install it. If a plug looks different from yours, the harness is for a different version.
Can I add a USB port to a motorcycle?
Yes, accessory USB ports exist for bikes. They need power from a fused source, ideally one that switches off with the ignition so it cannot drain the battery. Follow the instructions supplied with the port.
How should I route a new wire harness?
Keep it away from heat, sharp edges and moving parts such as the steering, and secure it with clips or ties where the original was secured. Leave enough slack for the bars to turn fully, and do not pinch the wires.
