Factory ammeter

So a lot of folks have a gauge cluster under the dash, so I have been installing a high quality, modern ammeter (along with a volt meter) under the dash for some time. You can use he original ring connectors and then just leave the factory ammeter in the dash for looks. Between the ammeter and the voltmeter I can keep a close eye on my electrical system, just like I do with a mechanical oil pressure gauge and the factory idiot light.
