1982 Honda CB650SC Nighthawk Main Wiring Loom

This main loom has an explicit 1982 CB650SC application and replaces reference 32100-460-340. Record the existing connections and routing before removing the old harness. A different CB650 variant or later Nighthawk may have another loom, and modified equipment needs its own compatibility check.

1982 Honda CB650SC Nighthawk · Nighthawk Wiring Loom Buying guide

Use the exact loom reference before comparing connectors

The selected harness is specific to the listed model and year. Identify splices, replacement controls and changed charging parts on the motorcycle so a main-loom purchase is based on its actual electrical configuration.

Do not broaden the harness application

The product explicitly identifies the 1982 CB650SC and warns that other years and types differ. Keep that narrow range intact. A shared engine capacity or Nighthawk name is not evidence that an earlier Custom loom or later-model harness can be substituted.

Plan around modifications already present

Keep the old harness available for comparison and document changed plugs or splices. Use the correct wiring diagram to establish circuit functions. A new main loom does not automatically establish compatibility with an aftermarket gauge, lighting conversion or altered switch assembly.

Main wiring loom questions

Is this the same reference as the CB650C loom?

The selected Nighthawk loom uses 32100-460-340. Choose by the exact model application and actual connections rather than assuming another CB650 variant’s harness is equivalent.

Will it support every aftermarket accessory without changes?

Check each accessory’s requirements and connector functions separately. The main-loom application does not verify every custom electrical component that might be added to the motorcycle.

What should I record before removing the old loom?

Note connector positions, wire routes and previous repairs or splices. Keep that information and the old harness available while comparing the replacement with the proper wiring diagram.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
