Hello
This is an extract from my wiring diagram from your model.
The black wires are earthed to the frame.
Red wire +ve from the fuse box
Light blue wire is from the rectifier (charge light)
Blue/black wire is from the oil pressure switch
Brown wire is from the headlamp/LH handlebar switch
Green wire is from the lights/LH handlebar switch
Purple wire is from the neutral switch on the LH side of the gearbpx
I can supply you with the full diagram check out my thread click here
Let me know if you would like one.
Best wishes Chris
