Amp meter guage - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck came with one of those trio guage sets in it that mounts under the dash. It has the oil pressure, H2O temp, and amps. The amp guage is not hooked up and I have no instructions with it. Does anyone know what it wires to? Also I have an alternator which has the red wire to the back and a two wire plastic plug that plugs in to the top. The plug has been cut off and my wiring harness has only one wire running up to the alternator plug, what is the second tab used for in this plug?
