1970 Honda CB750K · Wiring Harnesses Buying guide

Choose the main loom or a local CB750 wiring repair

The main loom, stator harness and oil-pressure lead repair different sections of wiring. Identify the damaged section and compare the connectors before replacing more of the loom than the job requires.

Assess the model-specific main loom carefully

The main loom’s stated application is 1969–71 CB750K. A changed switch assembly or charging component can introduce a connector mismatch even within that range. Record those modifications before ordering a complete loom.

Review component wiring before expanding the order

The stator harness has a seven-wire plug. The oil-pressure lead includes its rubber cover. Check the wiring section that needs repair so a local damaged lead does not automatically become a full-loom purchase.

Questions that help you choose

What matters if my bike has replacement switches?

Compare their connectors and wire routing with the early main loom. The 1969–71 application identifies the intended motorcycle arrangement; it does not establish compatibility with every later or custom switch.

How do I identify the stator wiring section?

The offered component harness uses a seven-wire plug. Compare the existing connector and the damaged section with that harness before choosing it instead of a main loom or charging component.

Can I retain the oil-pressure switch when replacing its lead?

The lead and rubber cover are sold as a separate assembly. If the fault is confined to those pieces, that purchase does not require a new switch; confirm the fault before selecting the parts.

Not sure which part you need?

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