Pertronix III set up

I mean it seems like it would make sense. Bringing the ballast wires to a single point seems to just eliminate them as they are not used. Meaning the 12V hot wire im looking for that is going the coil (brown) is the only one I need. Ohm resistance would be determined at the coil which means there should be no overheating. If it was a standard coil it would over heating would make sense.
I have attempted to explain. You go "eliminating all wires" and you will find there are other things "in there" the no longer work. Like, maybe, the alternator.

Let me put this another way........start "backwards" from the ECU connector (igntion box) Carefully untape as you go from the ignition box towards the ballast. Eliminate wiring hooked to the ECU. If you come across an in harness splice do NOT eliminate from there "forward." Then splice what's left all together at the ballast.

I will give it a shot in the morning and follow your instructions. After I remove the ECU box and its wiring being sure not to remove a wire beyond a harness splice. Once I get to the ballast wires I will post a pic to confirm which will get spiced together.
