Hitachi made/makes several different 12v alternators. Where did you get it?
Snyder mentions replacements for the Mitsubishi style alternators that had the external regulators.
Texas T has some instructions for their DELCO Model T alternator https://www.texastparts.com/mm5/manuals ... LT-12V.pdf

The hitachi alternator requires an additional wire or two for the exciter - the Delco is a single wire. THe do not wire the same

Can you post a picture of the external voltage regulator and what model Hitachi Alternator you have. There are lots of different ones for each.
