on my toyota i got all autometer ultralite pro comp II gauges. for mine i ordered the electrical ones for oil, water etc.
you'll have to get either 2 multimeters or 1 with long ass cables. then from whatever sending unit you're shooting from...let's just say oil pressure, you hook up one multimeter. then from your factory harness where it plugs into your cluster you try each wire separately until you find the one with resistance (i'm talking ohms by the way). then you know which wire to hook up to that gauge. go wire by wire for each unit you're trying to hook up. mine has the mechanical speedometer so that was easy, but it's even the same for the electric speedo too.
being a chevy you'll be lucky that you most likely won't have to change any of the sensors, but if you do...they come with the gauges (at least the pro comp II oil & water temp ones i got) as they're different ohm sweeps than imports.
i hope that makes some sence & if not, feel free to hit me up.
