Gauge Wiring
It's really very simple. I have not done it to a Corvette's amp gauge but in theory they are all the same. The amp gauge has one or two power wires. You will only need one of them for the volt meter. Then you need a ground. Some amp gauges didn't use a ground so you may have to run your own from a good ground location or the battery. The two gauges test two different things of the same system but the readings come from the same power. Amp gauges reflect current. Volt meters reflect system voltage. They both use power and ground wires from the same system.
