As I remember thats a replacement for the old regulator with new electronics.

(2)wires to the reg. 12volt+ input, (1) field wire output, ground the case(chassis)

If you are using that with a newer 2 field terminal ALT you will need to ground 1 field teminal on the ALT and run the other field terminal to the regulator field teminal.

The newer 72 up style REG works different field for ALT grounds thru the REG. They do not wire the same.
