The wiring will be different depending on what amperage alternator your car has, and if you have sport cluster or not. Need more info.

This may help, although this image is from a '75 shop manual. Good luck

Yeah, It's a Hybrid...It burns gas and tires.

The diagram posted above by aquartlow, is the same for a 73. You need the diagram for an ammeter charging system.

The I terminal is not used on a sport cluster car. 

The A terminal is battery power to the regulator. The wire is yellow with white dots. It goes to the battery power side of the starter solenoid, and usually has a fusible link at the end. 

The S terminal is key power from the ignition switch.  It should be green with a red stripe. 

The F terminal goes to the Field terminal on the alternator. It should be orange with a light blue stripe.
