Use the wire that's currently attached to the output of the "regulator". (It's actually a cutout relay) Attach it to the output of the alternator, and no other modifications should be required. Pretty soon a self-appointed "expert" will be along to tell you how the original equipment ammeter will suddenly become the source of so much heat the entire dash will melt and cause a 3-alarm fire. Ignore him.
