This could be intresting.......94 2.5L?

Is the oil pressure sending unit on the side of the block between the dist. and the ac bracket? If so there is a threaded hole there on my engine. (Can we say spewing oil out the block?) What I think my 2.5L is an engine with idiot lights...... Does the temp sender in the t/stat go to the guage, the computer, or both? Seems like I read the tstat one only tells the computer the temperature. If so will the one on the back of my 84 block work with it? Getting really close to trying her out. Cross your fingers.
