Right behind the water pump, on the drivers side,on the little shelf and there should be a dark blue wire dangling off the top...it stands up vertically, skinny where it threads into the block and fat at the top-about 1 1/8" takes a special socket to un-screw unless it is junk then vice-grips work great...

Hmmmm
I could have sworn that was the water temp switch. Right now I have no wire reference as the engine was recently totally rebuilt. My fear is that the machinist removed the oil sensor switch and put a bolt in its place in order to seal the hole while he worked on it.
