i've been trying to wire this gauge with no luck..need help please. the gauge is on a 1977 kingfisher with a 85 hp evinrude, it has a built in tank. On top of the tank there are 2 wires(gray and yellow). I know one is a ground and i guess the other goes to the sending unit. Then the gauge has a place for three wires, i know one of those is a ground but don't know about the other 2. How does all of this wire together.. Any help would be deeply appreciated
