1974 Duster Ammeter Bypass

OK. I searched previous forums and was unable to find any threads addressing this. Perhaps I missed one and if I did, my apologies.

So I'm wiring up the Painless Mopar wiring harness #10127. I am needing to know how to bypass the ammeter. The Mopar Painless guide was apparently written by folks who don't have a clue either. It has been quite an ordeal filling in the blanks between Painless wiring instructions and MyMopar 1974 Valiant shop manual wiring diagrams.

How is the instrument cluster getting battery positive power? The ammeter is a separate circuit altogether correct? Thanks for the help FABO members.
