Not charging after MSD 6AL installation.

Hello there sir,2 question for you,first do you need the ballast and second on your diagram,I know one wire goes to the voltage regulator,where does the second one goes too and thanks for the great help
I think you are asking about the original factory connections.

It depends on the year and model.
Functionally its like this in the most basic form; but the actual junction locations were moved around - sometimes using a splice, sometimes joining at a terminal.
