1974 Honda CB450K Left Control Attachment & Wire Route

Identify the left control mount and electrical terminations retained on your 1974 CB450K before choosing this replacement assembly. Its black finish and Honda reference describe the intended part, while the external wire route needs its own installation check on the bars actually fitted.

1974 Honda CB450K · Handlebar Switches Buying guide

Compare the left attachment and externally routed wiring together

The black clutch-side assembly references 35250-300-033 and states that wiring runs outside the handlebar. The description does not give full clamp dimensions or a CB450K-specific loom diagram. Its generic linked product guide still requires comparison with the motorcycle’s retained connections.

Honda CB Bar Switch Assembly ~ Left (Clutch) Side ~ Replaces 35250-300-033 Left clutch-side assembly with an external wire routeBlack bar-switch assembly references 35250-300-033, with wiring expressly outside the handlebar. Match the bar attachment, neighbouring control clearance and retained electrical terminations. Complete clamp measurements and a year-specific CB450K wiring map are not provided.View part

Identify wire-routing needs before selecting the replacement control

Compare the path required outside the bar with the controls, bar fittings and terminations staying in use. Earlier wiring routed inside the handlebar does not describe this replacement’s stated arrangement. Confirm the reach and clearance needed by the external route before ordering for a changed installation.

Use the linked guide alongside identification of the retained loom

The product’s instruction sheet names wire descriptions without identifying a CB450K year-specific harness. Establish the connections required by the wiring actually fitted, including earlier repairs or replacements. Its generic descriptions do not document every interface on this motorcycle.

Left-control mounting and wire-route questions

What should I measure when another left control has been fitted?

Compare the retained bar attachment and adjacent control space with the intended assembly, then confirm missing clamp dimensions. Reference 35250-300-033 identifies the replacement but does not provide a complete mounting drawing for every substituted control arrangement.

How do I assess wire reach with a different bar shape?

Identify the external path from the replacement control to the retained loom and establish the reach needed by that bar layout. The description specifies external wiring without a full route-length drawing. Confirm the missing measurements before choosing it for relocated connections.

What needs checking before applying the linked wire guide to repaired wiring?

Identify the retained harness and any terminals changed during earlier work, then establish the actual connection mapping. The sheet is a generic product guide without a named CB450K year diagram. Use that scope when comparing the replacement with repaired loom connections.
