1974 Honda CB550K · Wiring Harness Buying guide

Match the harness to the section you are renewing

The main loom lists the 1974–75 CB550K only. The dash harness and front brake switch lead are smaller, separately described items. Their presence alongside the main loom does not mean they are included with it.

Confirm the model range for each separate harness

The main loom’s stated range is 1974–75 CB550K, while both smaller harnesses include the 1974–76 CB550K. Those ranges do not make the products interchangeable. Compare the original reference and the section’s connector arrangement before choosing which wiring piece needs renewal.

Keep the supplied bulbs distinct from the dash assembly

The indicator harness comes complete with bulbs and has its own two replacement references. It is wiring for the indicator panel, not a complete instrument or switch assembly. Compare the existing sockets and connections with the product photo before dismantling the retained panel.

Wiring Harness questions

Does this main loom cover all CB550K years?

Its listing specifies the 1974–75 CB550K and replacement reference 32100-374-000. Later CB550K years are not stated for this loom; compare your motorcycle’s actual model and existing harness before ordering, especially where wiring has been altered.

Are bulbs supplied with the dash indicator harness?

Yes. The dash indicator harness is described as complete with bulbs and replaces 37581-323-000 and 37581-374-670. That contents statement applies to this separate harness, not to every wiring product or to a complete instrument panel.

Do I need the main loom for a front switch lead repair?

The front brake switch sub harness is available as a separately described lead replacing 35345-319-000. Inspect the affected wiring section first; a fault confined to that lead does not establish that the main loom also needs replacement.

Not sure which part you need?

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