wiring question
Thiis one even has a clock!!!
because of the issues with the factory gauge and the fact that I think that to have a finger on the pulse of your electrical system you need both an ammeter and a volt gauge, I have left the factory ammeter in place (disconnected) and put an under dash set of gauges in each of my Darts - volts, amps and mechanical oil pressure. If your charging system fails, a voltmeter will let you know that you are screwed after the voltage drops someplace that is below what you need, whereas the ammeter will show eratic or inappropriate charging well before your car is dead on the side of the road. The voltmeter is effective in detecting battery voltage that is too high or too low and allows you to try and address it before disaster strikes. My under dash ammeters are connected to those two wires - pull them down and see if they will reach were you want to put the gauge. No pigtail is needed, just use the original ring connector. You might have to cut some of the black harness wrap to get the length that you need.
