Unknown Sensor

If this is the Water Temperature Sensor,

Then what is this unknown sensor that came from this picture (the black one on the right)? When I took it out, coolant came out. It has two black electrical leads coming out of it and mine are diked off.

Any help greatly appreciated. I'd like to get it working again, whatever it is.

I believe it's the coolant temp switch.

I appreciate the info/link. I guess if you don't have an ECU, you don't need this correct?

If you want to have your choke and manifold heater correctly wired the coolant temp switchr is needed.
