[/quote]Answer this question first. Is your Pertronix powered at the coil or another place and if so where?

It has a positive and a negative wire that connect to the little coil terminals and then there is an extra positive wire plug that goes over the little positive post on the coil after the positive and negative wires are attached. For ignition perhaps? Then there is the larger coil wire that goes to the distributor that has the same 8 mm thickness as a spark plug wires.
