temp gauge problem again

[acl]

I know not another question like all the others. I am confused. Temp gauge does not move, always on the cold side and stays there. new, senser, new motor, but here is my real question. all the forums and other questions talk about wires and color and such but do these wires actually go to the gauge or somewhere else on the cluster " circiut board ". I have 4 "terminals" sticking out of the back of the gauge and not a wire going to any of them. I do have a wire from the senser going somewhere don't know where yet. Is this the problem? if it is can anyone tell me just what wire goes where and is there a way to hook up gauge just to test it to make sure it is a good gauge.
Thanks for the help
