The main loom, fuse box and regulator have their own references and specifications. A listed fuse-box package or matching connector shape does not establish every requirement of a modified electrical system.

Loom 73-0930 references 32100-460-000 and lists standard CB650 1980–82 and CB650C 1980–81 applications. Fuse box 73-0125 references 38200-MF9-405 and includes 15-amp fuses. Compare each assembly with the part fitted rather than transferring one product’s coverage to another.
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.
They describe the fuse-box package, not a circuit-by-circuit specification for the motorcycle or modified wiring. The listing does not supply that circuit map. Check the correct wiring information and required ratings before choosing protection for any changed circuit.
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.
