I've waded through a lot of posts and had a lot of questions on how to wire my alternator. Its WAY easier that I thought it would be - here's my experience on my 76 351W.
Purchased a 105A 1 wire alternator from quality power (http://www.qualitypowerauto.com/catalog.php?item=17). Make sure you get the correct pulley (I needed a serpentine pulley).
You'll also need some 4ga wire (I used long battery cable wire from the local parts store), a 175a mega fuse and a fuse holder.
Disconnect your batteyr and remove the old alternator. You can also remove the voltage regulator and associated wiring. See first pic for the "stuff" that I removed.
Next, wire up your fuse to the positive side of your starter solenoid, then run that wire to the red post on the alternator.
Don't forget to cut the old harness (pic 2) and run the black/yellow wire to the positive side of the starter solenoid so you retain power to your fuse panel. Pics three and four shows how I wired my setup. The other wires from the harness are not used and can be taped off. ** You will lose the use of your ammeter with this setup **
Thats it. Hook up your belts and you're good to go. Way easier that I thought it would be. Should take about 30-45 min if everything goes as planned. Might be a good idea to replace your old worn out battery cables as well.
