anyone have a idea on how one of the gm sending units that come in the Jazz fuel cells wire up to my aftermarket autometer gm gauge? I matched the gauge to the cell when I bought them 0-90 ohms, the gauge has the diagram to the sender with one wire, but I didn't get anything on the sending unit itself, there are two posts on it. any ideas? nearest to what I can figure from the gauge diagram, I just hook up 12v, ground and run the wire back to the sending unit on the cell (one wire)
