Hy oldblue51, the output wire from the alternator should go to the ammeter terminal opposite to the one the battery positive terminal is connected to (via a large gauge wire). There are a couple of different ways to hook up the alternator activation wire, there is something called "Da Plug" which is available from several suppliers, it contains a diode which will allow the ignition circuit to be interupted and allow the engine to shut down, if you use the ignition terminal of the ignition switch to activate the alternator. If your new ignition switch has an accessory terminal, you could use that terminal to activate the alternator, and I believe if you did it that way no diode would be required, hope that helps.
