I'm looking for help with wiring up my MSD 6AL box P/N 6420 to a Mallory Unilite P/N 3755101H. My coil is a Mallory Promaster P/N 29625. How do I begin? How can I tell beforehand if the units are even good or not? Is there any resistance or Ohm readings I should be aware of? Is there a schematic available for this configuration? Do I need a special resistor inline somewhere? I have a more or less stock 1965 Ford Ranchero 302/4speed. Thank you for any help you can offer.
