I assume your talking about the rectangular plug right at the alternator, and that your new Alt came with a short repair harness, the 2 heavy wires are BAT and the slim and likely white one is Tachometer AC sense, likely that 3 of the old ones were Bat test the old connector with a test light to see which of them have power to them.

Where does the wiring harness from the alternator on an 1984 Chevy Celebrity run to?

The wiring harness from a typical alternator has three wires. One is for grounding, one is from the battery, and the other is from the voltage regulator. In a GM alternator however, there may be two wires or only one wire. It depends on whether you have an external voltage regulator or not, and if the alternator simply grounds itself to the bracket it's attached to. The best way to find out is to trace the wires to their sources.
