1975 Honda CB750K Wiring Harnesses

Wiring choices for the 1975 Honda CB750K include a model-specific main loom and separate alternator, indicator-panel and oil-pressure assemblies. Identify the damaged section before ordering. These listings serve different circuits, and a smaller harness should not be mistaken for the complete motorcycle loom.

1975 Honda CB750K · Wiring Harness Buying guide

Choose between the main loom and circuit-specific wiring

The main harness is listed specifically for the 1973–75 CB750K. The other assemblies cover individual circuits with their own contents, making the connector and repair location useful starting points.

Use the main-loom application exactly as listed

The main harness page specifies the CB750K for 1973–75 and warns that other years and types use different OEM numbers. Compare your fitted loom, especially on a rebuilt bike, before using the model year to select it. A CB750F or later loom is not established by this listing.

Check what a smaller harness actually supplies

The alternator harness is a separate seven-wire assembly. The indicator-panel harness includes bulbs, while the oil-pressure assembly includes a wire and rubber cover. Match the damaged circuit and connectors first, then use these contents to avoid ordering a small assembly for a full-loom repair.

Common questions

Does the main loom listing cover every SOHC CB750?

No. It is listed for the 1973–75 CB750K and explicitly warns that other CB750 years and types use different part numbers. Compare the application and original loom before ordering for an altered or mixed-year motorcycle.

Are bulbs included with the indicator-panel harness?

Yes. The pilot-lamp indicator-panel harness description says it comes complete with bulbs. It is a separate dashboard wiring assembly, so do not treat it as the main loom or assume the other harness listings also include bulbs.

Does the oil-pressure wire assembly include the pressure switch?

The listed contents are the wire and rubber cover, with references 31270-300-154 and 31270-300-005. The pressure switch is a separate product. Check which part is damaged before choosing wiring, a switch or both.
