2 wire alternator

You should have a 2 wire alternator with a green wire that goes to the field side of your voltage regulator and a large black wire that goes into the center bulkhead connector. It sounds like that car had A/C at one time, which someone has removed. One belt should run your water pump and alternator and another should run your power steering pump. Just sight them from the sides and you`ll see what goes where. Hope this helps some.
