Frequently Asked Questions

Which Honda horn sub-harness does this replace?

It replaces Honda OEM 38105-369-000 for the 1977-1978 CB750K and 1977 CB550F Supersport.

Are the horn and main wiring loom included?

No. One horn sub-harness is included; the horn, main harness and switches are separate.

What should be checked if the horn still does not work?

Check the fuse, horn switch, grounds, horn terminals and supply voltage as well as the sub-harness. Repair corrosion, loose terminals or a failed horn rather than bypassing circuit protection.
