1971 Honda CB500K · Wiring Harnesses Buying guide

Identify the main loom or the smaller branch you need

The main harness references Honda 32100-323-020 for the 1971 CB500K. The indicator panel harness and front stop-switch sub-harness serve narrower circuits. Their listings do not describe a complete motorcycle electrical system with lamps and switches.

Choose the main harness by exact year and reference

The main loom listing specifically warns that other years can use a different Honda number. Use the 1971 CB500K application and 32100-323-020 reference together. Compare every branch and connector with the current motorcycle before installation, particularly where previous repairs have changed the wiring.

Order small branch repairs as separate items

An indicator harness includes its bulbs, but the front stop-switch sub-harness does not include a switch. These smaller assemblies are separate from the main loom. Identify which connectors and branches are damaged so you do not buy a whole loom for a local repair or overlook a required sub-harness.

Questions about wiring harnesses

Will a main harness from another CB500K year necessarily fit?

No. The featured main loom is listed specifically for the 1971 CB500K and Honda 32100-323-020. The listing warns that other years use different references. Compare the application and connections rather than relying on the CB500K name alone.

Which harness is intended for the instrument-panel indicator lamps?

Choose the pilot-lamp harness referenced to Honda 37581-323-000 and 37581-374-670. It is listed complete with bulbs. Compare the panel sockets and connectors with the existing assembly when selecting this local wiring repair rather than a main loom.

What identifies a front stop-switch wiring repair rather than a main-loom order?

The front stop-switch branch has its own Honda reference, 35345-319-000. Compare that small wiring section with the damaged part. Its switch is separately supplied; the main loom is another assembly, so identify the required branch before buying.
