Frequently Asked Questions

Which motorcycle and Honda OEM number does this main wire harness fit?

One main wiring loom is included specifically for the 1977 Honda CB750K and cross-references Honda OEM 32100-405-670.

Can a main harness for a nearby year or different CB model be substituted?

Do not assume interchangeability. Connector housings, terminal positions, branch lengths and sub-circuits can differ even between visually similar Honda CB years and types.

What should be compared before installing the replacement harness?

Disconnect the battery, lay the new and original looms side by side and compare every connector, terminal, wire color, branch and ground. Route and secure it using the correct Honda wiring diagram before reconnecting power.
