Introduction
The on/off switch on the handlebar is used to switch the dashboard on and off, if a key has been detected, and start the engine.
With the switch turned to "run off" (centre position), pushing downwards switches the dashboard on or off (activating the button inside the switch).
Wiring diagram

The button inside the on/off switch receives 12 volt power directly from the battery via the main 30 a fuse. When pressed, it sends the 12 volt power to the hands free system, which detects activation of the button. On/off switch pin 8, light blue wire (lb), on/off switch pin 5, red wire (r).
