Alternator issues

I ordered a new alternator for my 97 2 door Tahoe and it was different than the one I took out. A previous owner changed the plug and put a 200 amp alternator in. I also have a 94 2door diesel Blazer. The alternator in it matches the new one I bought. Also the alternator in the 94 is on the opposite side of the motor. Is this right? Are the serpentine belts different between a 94 and 97?

If the lettering on the belt still visible, you can see if they have the same number.
The number denotes the length.

As far as connector, you can always buy a pigtail matching the alternator and splice it.
As for the wiring, if you can post color, Glagulator can give you direction in less than a sec.

When I did the alt modification, I need to buy the pigtail connectors with all 4 wires and cut the 2 unnecessary wires.
As Glagulator suggested.

Those are hard to troublshoot since it is not stock setup.
