Nice work on the swap. I did this about last year and its been going great ever since. In regards to the plugs and terminals, the stock plug slots straight in. If you mean the B terminal when you say output one, you can actually unbolt it from the alternator and swap it over from the stocker.
The only issue I'm worried about is the Falcon alternator pulley is smaller than the stock one and thus spins faster than the stocker would. It *might* work the alternator harder and it *may* not last as long. More heat or wear out the brushes faster or something like that, but to me that seems insignificant.
P.S. The Falcon alternator I got is actually 110amp
