Ignition Switch Mystery Cable

[barbagris]

I have that plug on my bike as well, it has never been connected to anything from new .

Get a multimeter on it - see whether it has power! - could be usefull. Cant see one on mine.

Just checked the wiring diagram and it shows ...

Clock Connector

Heated Grips

Accessory Socket

Accessory Lights.

Could be one of those.
