Anyone interested in this conversion here's the info I was given:
Use the original, hot wire(10 or 12 guage) that bolts onto the post. Bolt it onto the new alt post. On the back of your new alternator is a plug. It will be 2 or 3 wires. There should be an "S" terminal and an "I" terminal. Jump the "s" over to the "I", and then run the "I" to an ignition source; There should be one going to your old external regulator, if you can't find it or have removed it, you can tap a source such as windshield wiper power. Make sure to use a diode in your ignition feed. You want this feed to go to alternator, not towards the ignition. This will make sure that when you turn the truck 0ff, the alternator will not stay on and kill your battery. That's all there is to it.
