replacing generator with maza 323 single wire alternatoraalternator

My 1963 Ford Econoline pickup has a regulator with the standard A F B terminals the only one I use is the B and that goes to the battery connection on the alternator. Question is my regulator also has a plug on the bottom of the regulator, where do those wires go and color codes would help, I waiting on my ford manual what I did on my Ranchero is leave the stock regulator in place disconnect the A and F terminals and ran the alternator battery to the B terminal. But I don't remember a plug at the bottom of its regulator. I'm thinking if I just leave the plug at the bottom plugged in and connect the alternator to the B terminal, I really don't have to know where the wires go (probably idiot light, accessory's and maybe ground) . My daughter wrecked her 323 and it has a real nice small alternator which ran allot more stuff than I will have on this pickup. And the FREE price is right![yay]
