If your converting to 12 volts, the DA Plug, also eliminates the need for the stock voltage regulator up on your fire wall.
The wire that went to the Battery terminal on the voltage regulator, now attaches to the alternator and the 6 volt regulator and the other wires attached to it, no longer need to be used.
I just converted my truck using this method. Note, the wires I no longer needed to use; I did keep in the harness, just in case I or someone else ever wanted to go back to completely stock.

So I went to Pep Boys and bought a delco alternator plug. Got it all wire up, but when I went to turn off the truck it wouldnt shut off with the key.
I came to find out that the aftermarket D.A. plug that the vendors sell has some kind of diode wired into the unit that allowed me to shut off my truck with the key. | | |

There are three terminals on the stock AD switch, they all get shorted together when you turn the key. Just make sure that the battery and alternator are on the same post and that the ignition system is on one by itself. I run my alternator with no DA plug at all, just insulated spade lugs on the wires to the pins in the alternator.
