200 Sensors/Wiring, need help!

[Keith Lawyer]

During the course of replacing my radiator, I think I
inadvertantly disconnected a few items in the engine
compartment:  behind and under the lower radiator hose
I see a silver bell-shaped object w/two terminals,
just under that is a sensor screwed into the block
w/only one terminal (oil temp?).
  I have two wires disonnected, a black/white with
black plug and blue/white with blue plug.  So, I have
two wires and three terminals to choose from!!
  I'm guessing one is oil temp as that gauge no longer
works. . . Any help is appreciated!!!

Thanx,
Keith L.
