The 130A 3G for a taurus will bolt up to cars with a 100A alternator bracket, but the mounting tabs are wrong for cars with a 65A alternator bracket. That's why if you have a 65A alternator you want a large case 3G that fits a 94-95 mustang (v6 models up to 2000).
    This is what I don't understand. My 3g alternator was from a 94 3.8 Taurus and I'm sure it was the small case because it bolted right up where my old alternator (which was a 65amp fire hazard one) was. The pulley was a little bigger (~1/2 inch), but it still worked. The mounting tabs matched up and the cases were exactly the same size; I measured them.

    So why is everybody saying that the 3.8 taurus is the large case alt? I'm very confused.

      Because normally they don't fit. 3.0 Taurus bolts in, 3.8 Taurus the bolts are an inch farther apart. maybe some years 3.8 Taurus had the smaller brackets or something.

        Maybe it was a 3.0 Taurus and I'm just an idiot. :drug:

          I looked at rockauto and the taurus 3.0 3G looks like it should fit the 65A bracket, the taurus 3.8 3G will fit the 100A bracket. The only difference between the 3.0 3G and the one for a mustang is the electrical connection orientation when bolted up.

          Should fit the 65A bracket:
          93-98 Taurus 3.0 (110 or 130 amps)
          94-95 Mustang v6 & v8 (130 amps)
          96-00 Mustang v6 (130 amps)

            yes please the more pics the better - if you can get one up close installed shot showing detail of how the wiring is run at the alternator, that'd be great

              I have a few pics of the swap done on a 2.3 Mustang turbo....if that helps, but I'm not sure how detailed the wiring is in the pics though

                I'm going to upgrade the radiator and cooling fan when I do the 3G swap, so I'll take a lot of pics before & after. I just need to go buy some wire and a fuse to run to the battery.

                    Question, what do you do for the low oil light wire, that is wired in with the alternator wiring?

                      How hard would it be to bolt a 100amp from a 90 MK VII onto a 90 vic frame? I know re-wiring would be involved. Just curious about dimensions and fitment.

                        You need the upper bracket off a police car. Those had the same 100 amp alternator. They don't have great low rpm output, so I'm not really sure I'd bother with one in all honesty.

                          Green wire is optional?? A 2G won't charge without it for sure, as switched +12V to the green is necessary to provide power to the field coils. I had assumed the 3G was the same way.

                            So the 3.8 Tortoise for sure used the large-case 3G? Just want to clarify since I'm still kind of in the dark on where the large-case models are to be found.

                              Not entirely certain, 91Waggin claims he got his 3G from a 3.8 Taurus Wagon and it was a small case 3G.

                              Yeah I know that this was true for my alternator. When I had the instrument cluster unplugged, the alternator did not charge the car. The amp light completes the charge cricuit for the 2G alternator, but if people we able to have their alternators, charging without the use of the green wire, then I guess it was changed.


                              EDIT

                              I retract my earlier statement. http://fordfuelinjection.com/?p=75 Apparently you do.

                                The green wire is neccesary. It goes to the ignition circuit and switches on the alternator. No green wire = no charge. Externally regulated models have the same green wire to the I terminal on the external regulator. Functionally there is no real difference between an internal regulator and external regulator. They have the same connections, just physically in a different place.
