1975 Honda CB550K · Wiring Harness Buying guide

When to replace the loom

The main loom, dash harness and front stop lead cover separate wiring sections. Compare existing connectors, routing and previous modifications before choosing one replacement or several, rather than assuming the main harness contains every sub-harness.

Main harness for 1975

The main loom listing names the 1974–75 CB550K and references Honda 32100-374-000. Compare the original connectors and route with the replacement, noting any non-standard accessory wiring or earlier repairs. The dash indicator harness and front stop lead remain separate selections.

Choose sub-harnesses separately

The indicator harness includes bulbs and lists the 1974–76 CB550K; the front stop-switch lead has its own replacement reference. Compare the affected section and connectors before choosing either. A main loom replacement alone does not establish that those separate pieces need replacing.

Common questions

Will the main harness fit a 1976 CB550K?

The main harness listing specifies the 1974–75 CB550K; it does not establish compatibility with the 1976 model. For your 1975 motorcycle, compare the fitted connectors and any wiring changes with the listed loom.

Does the dash harness come with bulbs?

Yes. The listing says it is complete with bulbs. It stands in for Honda 37581-323-000 and 37581-374-670 and lists CB550K bikes from 1974 to 1976.

What does the front stop sub harness connect?

It links the front brake light switch to the main wiring. It stands in for Honda 35345-319-000 and lists CB550K bikes from 1974 to 1976.
