The red wire of the DA Plug also goes to that same stud, it is there to tell the internal regulator what to do. The yellow wire goes to the positive post of the ignition coil. Tape all of the remaining wire back in the harness and they will be there if someone wants to restore everything someday....
As for the ignition coil most will say on the coil no external ballast resistor required. I use the Echlin IC64 which are very reliable and DO NOT need an external ballast resistor which is the weak link in the original ignition system. THat is why most people carried a spare in the glove box in the old days.
