2 options..

buy a one wire alternator...
I suggest getting one from powerbastards.com

or...
you need to run any 12v igntion on source to it and run thru a small light bulb first

Reviving a old thread here. If I use the Holley Pigtail with resistor Part Number 197-400 can I just hook that to any 12V Key on Source?
Thanks

Yes. I am using the same pigtail with the Dominator ECU. I actually created a 12+ output on the Dominator and connect that to the alternator through the Holley pigtail. I also added a terminal to the S post and ran that to the main power distribution point. This is optional, but desirable.
