1980 Honda CB650 · Electrical Replacement Parts Buying guide
The three assemblies have separate references and connection requirements. Keep the main loom’s listed application distinct from the regulator’s plug inventory and the complete switch’s key arrangement.

Main loom 73-0930 references 32100-460-000 and lists standard CB650 1980–82 and CB650C 1980–81 applications. The seller cautions against extending that coverage to other models or years. Compare the fitted controls and connectors when earlier modifications are present.
Regulator 24-2030 references 31600-460-731 / 31600-426-000. It has five wires in a six-prong housing and three in a four-prong housing. Compare the occupied wire positions as well as the two housing shapes. Switch 12-0051 is separately supplied with its fork lock and keys; compare its connector, wire arrangement and mounting.
The regulator listing gives its connections and replacement references but no battery-chemistry compatibility or charging-voltage limits. Obtain the regulator manufacturer’s specification and compare it with the fitted battery’s requirements before choosing it for a converted setup.
The switch listing confirms keys for its ignition and fork-lock assembly only. It does not promise a match to a separate seat or helmet lock. Confirm a key-matching solution before ordering if retaining one-key operation matters.
