Wiring Diagram

Hey, I'm trying to hook up a shift light on my busa and I don't have a service manual. Can anybody tell me what color wire in the harness running to the gages is the pulse wire for the tach. My bike is an 02 if that makes a difference.

there should be a empty plug somewhere off a sensor for that purpose but i could be wrong...

Taco wire at the instrument cluster is Yellow/Blue (this is out of the service manual) I'm used to it being called a tach, not a taco, but I guess something just gets lost in the conversion.
