Just disassemble the 3 wires on the separate connector.
Chances are they separate out on their own on one end or the other (either at the alternator or voltage regulator).
If they are all in one connector on both ends, you can usually get the crimp ends out of the plastic connector with a tiny screwdriver. The crimp ends are held in place by having a little bit of the metal bend and catch the plastic. If you slip a tiny screw driver in, you can pull the wires out w/o breaking them.
Once they are separate, disconnect one at a time and see what happens. Which ever one makes the battery voltage (or ammeter) fall, you found your field circuit.
Put the other two back in the connector and reattach them.
The other one can either be left off altogether; what I did is cut that wire in the middle, splice in a much longer wire, and put it on a switch on the dash so I can engage the alt from the cab if I have to.
