The main wire harness matches the 1981-1982 Honda CB900C Custom and replaces Honda OEM 32100-461-770. Other CB900C years use a different harness and should not be assumed compatible.

One main wiring-harness loom is included. Switches, relays, electrical components and separate sub-harnesses are not included.
What should be checked before connecting a replacement wire harness?
Disconnect the battery, compare every connector and branch with the original loom, clean ground points and repair the cause of any melted connector or blown fuse before applying power.
