A third generation 3g alternator with a built in regulator wires to the car basically the way, the difference being you don't have the wires between between the regulator and alternator to deal with. You do however, have the wires from the car to alternator's built in regulator which are fairly simple if you get the harness for the alternator. A power wire goes to the battery or solenoid, A second wire(trigger wire) that goes to the battery side of the solenoid, a third wire that runs from the alternator to the indicator light on your dash. a forth wire that runs from one terminal on the alternator to another terminal on the alternator. I have only used the one wire GM alternators on tractors and boats which is what they were built for(along with other utility equipment of course). In all my reading, I have never heard of an automobile being produced with a one wire alternator, but evidently many people use them.
Good reading on this site.
