Is the 3-pin connector a short cable close to the ECU? If so, it is the diagnostic plug and is normally disconnected.
I have a spare wire on the left side, which I think is for a sidestand switch that is not fitted.

johnboy888 wroteHi Griff, thanks for the pointer, I downloaded that, but it's the same manual that I already had.
On the wiring diagram ,there seem to be four wires going nowhere, three of them from a connector marked "A B C", and a fourth wore by itself. So I thought the diagram I has was incomplete.
Any idea what that's all about ?
Thanks
John
