1 wire verse stock multi wire alternator clarification

[culp71]

appreciate all the help guys thanks!

I do have one more question is there a separate connection I can make from a fused ignition on power source and route this to the ammeter, and not have it ran with any part of the charge circuit?
simply just a monitor on current power in the entire system?

The IVR on the back of the gauges has a switched 12v wire supplying power, it's terminal has an extra tab like it was meant for a voltmeter...
