    I am installing a tsp ready to run distributor and e core coil into my 74 scamp and I just want to be sure as to how to jump the ballast resistor. I made a jump wire assuming I needed to connect top post to top post and bottom post to bottom and it would make everything right but I want to be sure as all that I have read is quite confusing on the forums and everywhere else. PLEASE HELP BEFORE I END UP BURNING MY CAR DOWN LOL Screenshot_20191217-020006_Chrome.jpg Screenshot_20191217-015942_Chrome.jpg 15765663396008042940725798823418.jpg

    What gauge wire? Same as the harness? Yes?
    Good to go.

    You actually only need to jump one side. Here is the "deal."

    When the Mopar breakerless system was first introduced, and for a few years, the box received power TO the box from TWO sources...........full 12V and also reduced power through 1/2 of the 4 pin ballast.

    These are now known as a "5 pin" box and MUST have a 4 pin resistor

    MOST boxes you will encounter are a more modern 4 pin box and do not need a 4 pin resistor.......the section feeding the box is simply dead ended

    A 5 pin box MUST have a 4 pin resistor

    A 4 pin box (or a conversion like yours) can have a 2 or 4 pin resistor, the "other half" is not used.

    The 2 pin resistor is the same wiring which feeds the coil as the 4 pin. In other words once you forget the "other half" feeding the box, the half of the ballast which feeds the coil is THE SAME AS IT WAS ever since breaker points.

    To sum this all up, you only need one jumper. "Which side?" Just put a light on the coil + and turn the key to "run." Unplug the old ballast. Hook your jumper to the end with the jumper across the two end terminals, hook the jumper to one, then the other wire on the opposite end. Whichever brings the coil+ wire "alive" is of course what you want. Tape/ "safe" off the remaining wires

    So even tho I have a 5 pin ignition and a 4 pin ballast I sould wire it up as if if were a 4 pin ignition and a 2 pin ballast? I'm confused

    If you are converting from a Mopar igntion, yes. The ONLY thing the other two pins on a 4 pin ballast does is feed power to the ECU. I hope you understand that this amounts to TWO resistors, in the "same box." One fed the coil, the other fed part of the ECU.

      $80 you paid $79 too much that is the worst POS ever sold in the USA for a USA Car.
      Try ordering a part for it, try tech support, try taking it up to 6K RPM, try adjusting the mechanical advance limits, try adjusting the Vacuum advance.... why would you waste hard earned money on that Imported POS... just my Opinion.

      Buy me 6-8 whisky's and tell you how I really feel about that POS, in my current sober condition I'll hold back my true thoughts.
