Do you have a service manual? In the back is the electric schematic of the bike, and the color coding of all the wires is on that schematic.
Even if the service manual is not for your model year, it will probably work.
You'll probably find that each connector has one wire that is black with a white stripe. That's ground. If you post the color combination of the other wire I can try to look it up in the schematic of my '02.
