Question for the electrical savvy

[Bhelton]

So, no help in electrical section and I've searched a lot on here for my answer and haven't found what I'm looking for. So here goes....running a cs130 alternator and a EZ wire harness in my 72 I know what to do with the wires from the 4 wire plug but my confusion is the one wire from harness. The alt wire, I've seen it can go to battery or battery lug on starter and seen to put a fusable link in the wire. Is this true? What amp fuse if so? And then do I need to run a wire back from starter to alternator with the bypass wire from EZ wire that was included in kit?

Now unless I run a charge light in cab I've seen you put a resistor inline from exciter wire to the wire in plug. Is this correct as well?
