Roger, You only use three terminals. The white wire connects to the S terminal (which operates the ignition warning light), brown/green wire connects to the F terminal, brown connects to the A terminal. I am assuming you have the standard Autolite alternator control box. Do not forget to connect a ground wire to the base of the control box and run it to the engine block. The control box is mounted on a fiberglass foot box which is terrible at conductivity! AJ
