Hy. To add to the MSD connection topic, I used the original wire from the ign switch to the pos side of the coil(stock wire) as the connection to the red wire to 12v source from the MSD 6A box.
As you know, with the MSD set up, the ign switch does not go to the coil no more, but to the red wire of the MSD 6A box.
It worked excelent in my car.
Jaime.
