1979 Honda CB650 · Main Wiring Harness Buying guide

Keep the 1979 harness application exact

This main loom replaces reference 32100-426-770 and is specified for the 1979 CB650. Later CB650 years use a different reference, making an exact year check important before replacement.

Compare before removing the old loom

Record the existing branch routing and connector locations while the old harness is still available for comparison. The replacement is a main loom for the 1979 CB650, referencing 32100-426-770. Use the correct wiring diagram to distinguish original connections from later repairs.

Account for changes around the harness

A year-correct main loom cannot identify every control or lamp fitted by a previous owner. Compare replacement switches, charging components and any added circuits with the intended connections before ordering. Resolve those differences with the wiring diagram rather than relying on a matching connector colour.

Common buying questions

Is this the harness for a 1980 CB650?

Its stated application is the 1979 CB650. Later CB650 years use a different harness reference. Choose a loom verified for the exact year rather than extending this one’s application because the motorcycles share the CB650 name.

Which reference identifies this main loom?

The replacement references 32100-426-770. Compare that reference, the exact 1979 application and the connector layout together. An old harness may have lost its label or been modified, so the wiring diagram remains an important cross-check.

Will it connect to aftermarket switches and lamps?

That depends on the equipment fitted. This is a year-specific main harness, not a guarantee for modified controls or lighting. Compare each changed component’s circuit functions and connections before assuming it will mate with the replacement loom.

Not sure which part you need?
