Wiring diagrams can be invaluable when troubleshooting or diagnosing electrical problems in motorcycles. These Honda wiring diagrams are from our personal collection of literature and schematics. The copyrights remain with the original holders.

The color code legend in the chart applies to most, but not all Hondas.
