>From the looks of it, and the fact that no one puts an uncommitted pin in anything, my best guess is that is a single pole, double throw, an SPDT iow. If you can find two terminals with only an ohm or so, that would be one set of contacts that are closed when its not energized, and two terminals that show 50 to 200 ohms, then that should be the coil. When 12 volts is applied to the coil, the original 1 or 2 ohm connection isn't there any more, but you now have a connection from one of those 2, to the terminal left. Single pole, double throw.
