I tried that for my 1971 Dart. I had 2 brown wires on one side of the ballast (outer end) and 2 blue wires and a black wire on the left (inner). I tried tying the left wires and then took one brown wire of the two (the one that was not going to the bulkhead, but the one coming out of it) and connected that to the thin red wire of the MSD 6AL. I also took the blue wire out of the Voltage regulator and tied that also to the thin red wire to the MSD 6AL box. Still not working though. just swapped the 6AL box for a new one ..still not working.
