i was gonna guess that you meant alternator
the connections between various cars and alternators were slightly different, but being that every alternator in existance is ESSENTIALLY the same thing, it's proabably a different concerning location and type of connections for wires like you said.
that and amperage
otherwise, they all put out about 14 volts once you get the engine started. my car has a 60 amp alternator. if you switch to a more powerful one as some people do when they add appliances like televisions and premium sound systems, just make sure to read up on how much of a surplus amperage you can handle. i really don't know anything more on this topic.
other than that, the alternator's connection to the battery electrical system (battery cable and whatnot) would be the major obstacles, i think. if all you have to contend with are a +, a -, and a ground, you can mod any set of wires/cables for that to fit with easy to find supplies at hardware stores. if you've got some special harness with 4 or more wires connecting to the alternator, i'd make sure i knew what i was doing before i modded anything.
i'm really not basing any of this on any research, so... i'll leave the rest up to you.
