Big_Yellow_Tank 04-14-2008, 05:16 PM don't "tap" in - use one of these: This One (http://www.partsamerica.com/productdetail.aspx?MfrCode=DOR&MfrPartNumber=85613&CategoryCode=3067I) and it should be the negative side of the coil Good luck. snook 04-14-2008, 05:28 PM well the negative on the coil? Big_Yellow_Tank 04-14-2008, 07:56 PM eh? AFAIK coil has two "prongs" sticking out of one end. One should have a little "+" next to it and the other should have a little "-" next to it. Hook into the negative side of the coil for the signal for your tach. Depending on the tach it should have White: + Dash Lights On Red: + Ignition On Black: Ground Green: Signal (Negative Coil) | |
