I have a 91 G20, and I am going to hook up a couple of the Autometer gauges in which include vac/boost, voltage, and electrical oil pressure. My question is how can I hook those up? From what I understand is that, vac/boost to the intake manifold, voltage goes to the cigar. ligter,, and the oil pressure goes to the oil pressure switch at the block. But what about the light for the gauges itself. Where am I suppose to get the power from? All I know is that the negative goes to the body, but how about the positive wires?

I am confused. If somebody have done something like these please tell me the installation in detail. Thanks very much in advance.
