I am trying to figure out which wire off the coil is the negative wire for a tach signal for my cruise control. It says to hook up to the negative side of the coil, but we have 3 wires. From the schematics I am guessing it is the Bl/W wire. if there is anyone out there that knows, please respond. the G wire looks like a hot wire that shares with the tail lights. and the other wires go directly to the ecm. Need some help please 2002 Vfr800
