1972 Honda CB450K · Handlebar Switches Buying guide

Keep each side’s reference and wiring information together

The black left clutch-side assembly references Honda 35250-300-033 and uses wiring outside the handlebar. The right brake-side assembly references 35300-319-670. Its description does not itemize individual operating functions or provide a complete connector and terminal specification.

Use the linked left guide without extending its application

The left listing provides a wire-identification guide that does not name a motorcycle year or model. Check it against the retained wiring and resolve ambiguous functions before planning a connection. It does not identify the right assembly’s layout or establish a model-specific CB450K wiring conversion.

Assess a control change at the housing as well as the wires

Compare the attachment of each proposed assembly with the retained bar and adjacent control. A different bar or replacement perch can change the available space and required wire reach. Confirm any missing dimensions or termination details before selecting either side for those altered components.

Control-side and wire-route questions

Does the right assembly’s description document its individual switch functions?

It identifies the right brake-side assembly and its Honda reference, but does not provide an individual function map. Establish the functions and wiring connections required by the retained installation before ordering for custom electrical work. Do not infer them from the small product photograph.

What should I check when changing from internally routed left-control wiring?

The offered left assembly explicitly routes wiring outside the handlebar. Compare the new route, control attachment and retained harness connection. Confirm the reach and mounting details needed by the proposed layout; no internal-to-external conversion steps are documented in the description.

Can the left instruction guide settle a changed right-side connector?

The linked guide belongs to the left product and has no motorcycle-specific application stated. Check the right assembly’s own reference and required connection information separately. Resolve the altered terminal layout rather than assigning the left guide’s wire descriptions to the other side.
