If it's a stock type alternator the #2 terminal loops to the battery terminal to the battery. The #1 terminal will go to the alternator light and the other side of the alternator light should go to the ignition switch for power in the key on position. This circuit switches the alternator on through the bulb. If it's a 1 wire alternator you don't use the small terminals.
