1981 Honda CB750K Main Loom & Connection Harnesses

Only three distinct wiring products form this 1981 CB750K selection: the main loom, ignition-coil sub-harness A and horn sub-harness A. Identify the damaged section first. The coil connection listing explicitly says it is not included with the main harnesses, which matters when planning the order.

1981 Honda CB750K · Wiring Harness Buying guide

Choose the whole loom or the named connection section

The main loom lists Honda 32100-425-770, while the two smaller harnesses have different references and described destinations. They are separate purchases rather than interchangeable names for the same motorcycle wiring assembly.

Use the coil-harness exclusion literally

The coil sub-harness plugs into the main harness and connects to the ignition coils, according to its description. It is expressly not included with the main wire harnesses. Inspect that connecting section when renewing a loom so the order can include the separate part if it is also needed.

Identify the main-loom application before buying

The main harness description gives Honda 32100-425-770 for the 1980–82 CB750K and cautions that other years and model types can use different references. Compare the present loom and connectors. The horn and coil harnesses solve named smaller wiring jobs and should not be treated as a complete main-loom substitute.

Common questions

Does the main loom include ignition-coil sub-harness A?

The sub-harness description expressly says it is not included with the main wire harnesses. It has its own replacement reference and connects the main loom to the coils. Order that separate section when required for the work.

Is the horn sub-harness a complete motorcycle wiring loom?

It is described as the harness that attaches to the horn and replaces Honda 32101-438-000. The main loom is a different listing. Identify the damaged connection before deciding whether the horn harness is the appropriate purchase.

Does this main-loom listing establish fitment for every DOHC CB750?

It specifies the 1980–82 CB750K with Honda 32100-425-770 and warns that years and model types can differ. Compare the actual application and connectors; a shared DOHC engine description does not establish universal loom interchange.
