The 12volt to your starter relay has a feed from the Battery through a fuse to the ignition switch Red wire, this then feeds the starter button on the right hand multi switch green wire, a Black and yellow wire then goes to one side of the starter relay,
The 0 volts to the starter relay (interlock) comes from the frame/ batt Neg and first goes to the Neutral switch then side stand switch, these two switches remove the 0 volts from the brown and black wire if the bike is in gear or the side stand is down, the clutch switch overrides these two switches by applying a 0 volt to the brown and black wire which then goes to the starter relay,
So if you put a wire from the frame or the neg 0 volts side of the battery to the starter relay terminal with the brown and black wire on it the press the starter button with the ignition on it should start.
