Single Wire Alt setup to 65 Barracuda Harness

Yea I got to play with it this weekend. It has a two wire plug that was unplugged from the harness.
I took the harness off and clipped the pigtail and left it in the alt plug.
I'm not looking to do a crazy setup I just want it to work with my system. So I'll probably leave the regulator if that's possible.
If i have read the posts right above that the Efi ecu regulates the charge and it is not internal to the alt, then I should be able to run it just as the stock (for this yr and model) alt was, as long as I get the wires right when grafting in the pigtail....

Right???? :-D
