Today we tried pulling the Ignition Control box, (seen in last picture with the black goo running from it) and swapping it out with one from our running parts car, a 75 four door Dart. Still having the same issue so I don't believe the Ballast Resistor or the Ignition Control Box are the causes. What are the "bulkhead connectors" and where are they located? Might sound like a dumb question but I honestly don't have a clue. Is that a grounding strap?
