The clutch switch/wires assembly is located in the housing where the clutch hand lever is mounted to. You will find a looong 2 wires lead coming out of that housing routed towards the shelter. Unplug those 2 wires lead male connectors from their respective female harness connectors and check for continuity through those same male clutch switch wire connectors with your always handy ohmmeter.
With the clutch lever in the clutch engaged position, you should find a reading of almost infinite resistance: an open circuit.
With the clutch lever in the clutch disengaged position, you should find a reading of almost zero resistance; a closed (or completed) circuit. It is a plastic plunger type switch that slowly became very sensitive to clutch lever position on my trike.
If you find the switch isn't operating correctly, the clutch switch/wires assembly is still available through the Honda OEM parts system. Around $10. I'd advise you to proactively replace it anyway. The OEM Honda part number is 35340-329-003
Let us know what you find.
If needed, We can give you further information about its replacement procedure.
