Ok Im absolutely be wildered right now trying to figure out where I went wrong. I have two brand new Greddy 52 mm guages. I just finished installing them on the a-pillar. I hooked up my 12 v constant to the cigarette lighter, 12v ignition to the fuse box, and my light source to the little light that plugs into the spot right by the key for the ignition, and the ground to a common chassis point. My guages come on, or atleast the lights do, but the needles dont move at all... Anyone have a clue as to whats up?

What type of gauges are they? What type of signal are they receiving?
