I have seen similar discussions on how to wire the pacs (last December) and everyone was confused. I believe there are 2 pacs on the market. The Drake rally pac needs to be wired to coil (as per Mustang monthly article, because they could not get an air-core tach to work properly). There are a few retailers that sell this type of pac. The non Drake rally pac (it has the FORD on the tach) wires thru the loom and it has nothing to do with if it is a 65 or 66 pac. So your rally pac that wires to coil probably does not have the FORD on tach, is this correct? My problem is that I have a Mallory electronic dizzy and have been told it needs to be wired to coil as a negative coil trigger (Drake type) , otherwise if I use a FORD type, it will blow up (because it wires thru loom).Does anyone know the answer? Can you connect the ford type to coil instead of thru harness ?? Does anyone know??
