1981 Honda CB650C Custom Main Electrical Loom

When replacing the main loom on a 1981 CB650C, record the motorcycle’s existing electrical layout before removing it. The listed harness has a specific Custom application, but previous control, lighting or charging changes may need connection checks that the frame’s model year cannot settle.

1981 Honda CB650C Custom · Main Electrical Loom Buying guide

Compare the harness against the equipment it must connect

The main loom uses reference 32100-460-000 and lists the 1980–81 Custom. Keep those identifiers tied to the actual connected assemblies, especially where older splices or replacement switches obscure the original wiring pattern.

Document modifications before replacing the loom

Keep a record of non-original plugs, splices and accessories. Compare each affected circuit with the correct wiring diagram and retain the old harness for reference during the repair. A new main loom cannot identify the intentions behind a previous owner’s modifications.

Use the listed model range narrowly

The product includes 1980–82 CB650 and 1980–81 CB650C applications. It warns that other years and types differ. Do not extend the claim to a Nighthawk or another engine-capacity match without checking the appropriate harness reference and connectors.

Main Electrical Loom questions

Is the 1981 Custom explicitly listed?

Yes. The written application includes the 1980–81 CB650C Custom and reference 32100-460-000. Compare its connections with the actual motorcycle before ordering.

Will it establish compatibility with new accessories?

No. Check each accessory’s electrical requirements and connections separately. The main-loom application does not verify every added lighting unit, instrument or control.

Should I discard the old loom before the replacement arrives?

Keep it available while comparing connector locations, routing and past repairs. Record its connections before removal so the replacement can be matched using the proper diagram and service procedure.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
