Hello all

I'm swapping an 03 4.6 2v into my 72 F100. I'm going to be running the Holley HP EFI so most of the wiring is plug and play. What would be involved with the alternator wiring? I know there is a lug on top as well as a 3 wire plug. What all has to be wired for the alternator to function? Just the big power wire to the battery?
