1974 Honda CB750K · Wiring Harnesses Buying guide

Identify the main loom or the sub-harness you need

The main loom and smaller wiring assemblies are separate products. Match the damaged section to its listing, using model-year application and connector details before deciding how much of the wiring needs replacement.

Use the main loom’s precise year application

The main harness listing is specific to the 1973–75 CB750K and replaces 32100-341-703. It explicitly notes that other CB750 years and types use different references. Compare the original part and connectors, especially if your bike has an engine, switch or harness from another model.

Check the smaller assembly before replacing the whole loom

A damaged alternator connector, dash-light section or oil-pressure wire may call for a separate assembly. The alternator harness is listed with a seven-wire plug, and the dash harness includes bulbs. Identify the affected section and compare its connections before assuming the complete main loom needs replacement.

Common questions

Which connection should I compare for the stator sub-harness?

The alternator harness has the described seven-wire plug and replaces 31110-300-154. Compare the fitted connector and the affected wiring section before ordering the sub-harness instead of a complete main loom.

Does the dash-light harness come with bulbs?

Yes. The featured indicator-panel dash harness listing states that it comes complete with bulbs. Compare the existing panel and connectors with its listed application, particularly if the instruments were changed on an earlier custom build.

Can I use a main loom from another CB750 year?

The featured main loom listing warns that year and model differences matter. It is listed for 1973–75 CB750K. Use the correct reference and compare connections rather than treating all SOHC CB750 harnesses as the same product.
