If you did not get a single long black wire (about 4') with it when you bought it, chances are good that the previous owner did not need it. That wire plugs into the CDI, and thats where the pulse comes from to make the tach work. '02 needed the wire, I guess either some or all of the '03 needed it too. Maybe someone on here still has the wire if they didn't need it. If I can find the directions I'll scan them, but if not then it's going to be a few days before I pull my tank off, I'll take some pics for you. I have a feeling you're going to need that wire.
