The wire color sheet I posted for you on the website showed the green wire at the coil pack as the tach signal (+) and showed the 12v+ for the tach. I assumed you would know to ground the tach to any good metal surface. Go back to the web site and look at my reply to you for ALL wire colors for that vehicle as provided by D.E.I.'s website.
