Welcome to the forum wcerqua! 
As has been mentioned many times before the 130A 3G alternator swap out of a early/mid '90's Taurus will fit right in with a cable & fuse + a simple harness modification.
... And do away with that fire hazard plug on the back of the 2G.
There are several configurations, so be sure you get the right one.
A recent thread here reminded me just how important it is to do your homework.

There are at least three styles of 3G alternators, you need to pick the one that matches the style of alternator that you have in your truck right now:
a) if you have a pivot-mount small-frame alt (7" distance between mounting holes) you need an alternator for a mid-late-'90s Ford Taurus with the 3.0 V6 engine.
b) if you have a pivot-mount large-frame alt (8-1/4" distance between mounting holes) you need an alternator for a mid-late-'90s Ford Taurus with the 3.8 V6 engine.
c) if you have the side-mount alternator you need an alt for a '97 PSD.
These are all 130-amp alternators, there are also 95-amp 3G units in existence but they are not what you want even tho they will bolt up if you pick the correct one.
