1980 Honda CB750C Wiring Harnesses

The main wire loom offered here is specifically for the 1980 Honda CB750C. Keep that exact-year application separate from the ignition-coil sub-harness, which is a distinct connecting section. Inspect what is damaged or missing before assuming one loom replaces every wire on the motorcycle.

An exact model-year main harness

The main loom is for the 1980 CB750C; other CB750 model years and types use different harness references. Preserve that distinction when restoring a motorcycle assembled from more than one donor bike, and compare all retained electrical components before installation.

Sub-harness A is separate

The ignition-coil sub-harness connects to the main loom and the ignition coils. It is explicitly not included with the store’s main harnesses. Inspect this short section and order it separately when your electrical restoration requires it.

Wiring Harnesses questions

Is this main loom suitable for a 1981 CB750C?

The product is specified only for the 1980 CB750C. Use the correct model-year harness rather than assuming adjacent years share the same wiring.

Does the main loom include sub-harness A?

No. The coil sub-harness is explicitly separate from the main wire harnesses. Add it if that connecting section is missing or needs renewal.

What should I check on a modified motorcycle?

Identify the engine, controls and charging parts actually installed, then compare their wiring with the 1980 diagram and loom. Resolve mismatched components before treating the replacement as a complete wiring solution.

Not sure which part you need?

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