MSD 6AL Wiring and Ballast

Thank you. Very appreciative for your knowledge. I believe my alternator is for after 1970 with 2 field wires. I just used one to ground and the other to voltage regulator. See pic below.
I believe I would use both fields if I wanted to convert to the post 1970 triangle type connection voltage regulator? One field would connect as usual with green wire in my pic above. The other field would connect to the voltage regulator as well?
