Binger, is the 12V harness you mention similar to the original wiring? If so then the wire from the alternator will come up to the ammeter then go out. Current will go thru the ammeter, but you will have to connect the wire from the alternator to the wire going out to fuse block and tap off that point for the voltmeter and run the other side of the voltmeter to ground. You cannot wire the voltmeter in like the ammeter is now.
