With the 2 plug in wires, Field & Ground it doesnt matter which plug they are on. They can be reversed and your alt will still work great.
From book " the isolated alternator is so called because it has a field winding that is not grounded in the alternator. Each end of the field winding is connected to isolated terminals on alt. One field terminal is supplied with battery current whenever the ign is turned on. The other field terminal connects to the regulator which provides a regulated ground to control charging voltage."
Therefore it doesnt matter which terminal the blue or green wire connect to. They are connected inside the alternator anyhow. The electricity doesnt care which direction it flows inside the field.
Just make sure the battery connection is correct. One blue on the field and green on the other terminal.
