VNB6 conversion from 6 V points to 12 V electr Ignition

I have converted muy VNB6 to 12 volt with the Bajaj kit; does anybody know how to wire this one to the loom on the VNB? I need to connect the Yellows, Dark Blue en light Blue from the loom but where to? I am assuming the red and black are power and grounding; the Bajaj kit has violet, grey and red...what is grey and vioilet? does anybody know? THANKS; I can send a picture.
