Download the FSM for your year from the link in my sig. There are only 3 wires that go to the stock alt, a pigtail tee connector and a power wire that goes to the battery.

My S1 alt was the same, had the 4-pin plug with one or two missing - being an externally regulated model.

If you're planning on modding the car e.g. adding any electrical things like stereo amp, thermofan, etc.. you're better off upgrading the alternator to a later model internally regulated alt from e.g. s4. Can get you diagrams for the upgrade if needed, let me know.

Edit: get yourself a $20 multimeter, it's very handy for all electrical stuff and then you can test the voltage at the battery with the engine running, will determine the health of your alt
