I'm pretty sure that you have a denso alternator... which model is it? the newer Chrysler cars had densos. denso comes in a 160 amp size...
those are self regulated with a sense wire. they do not use an external voltage regulator....

basically, one wire goes to the battery (the big one) they have a ground, the sense wire senses the voltage wherever you connect it and the alternator adjusts itself to make the sensed spot have the right voltage. sometimes they have a L wire which is for a charging indicator light. the Ig should get powered when your ignition is on, this enables the alternator.
