Okay, for my stereo stuff, I had a Supra alternator that was done to 100A, however...

That oil line isn't too hard to move temporarily.  I would simply disconnect it at the cylinder 
head, move it out of the way, and plug in the connector.  Job done.  The wires don't stick out 
that far behind the alternator, IIRC, and I'm sure that you could wrestle the hose back in place 
once it's connected.

Actually, that looks exactly like the 100A alternator that I had, so it's possible that what I 
had wasn't a rewound unit, but the MR2 unit in the first place.  It was a real pain to get to 
that connector, I remember.

That alternator failed on me a few years back, and I've got an 80A 7M-GTE alternator in there now.
