I have looked all over for it. The manual says its a 3 wire deal.. I can not find any thing like that on the whole engine.
I see what looks like a sensor just above the oil filter. But its just a single wire and nut post sensor..

My Oil pressure gauge is pegged all the way to like 100... And I got a check guages light on...

 

yep its long and has a foam looking thing covering it. it is above the oil filter, mine has one wire.

 

That sensor that is in the location you are showing does not look like that one.
Mine has a threaded top with a nut holding a wire on.

Yours a 93? Mine is a 94 and saw that it could be up on the back side of the intake manifold area.. I going to look today and see if Its there..
My FSM shows it on the driver side of block right behind the engine mount...

 

You have the wrong switch, it's in the right place though (see the "Note" in the pic). Sounds like someone threw on an older vintage non-compatible one, which would explain the pegged needle. Your wiring is supposed to plug in, and looks like this....

 

Its only 1 wire to it.. I can not find any one wire sensors.. I been looking..

Here is what is in there... I will get a actual pic in a hour..

 

Edit:

 

Here is the one above the filter

 

I dont know what was done to this engine in the past or anything ...

Just trying to fix things as I see them.

If anyone has a link to the correct 1 wire sensor I will appreciate it please..
Cause ALL i am finding is the 3 wire ones... Part number or something like a link to it would be GREAT..

 

well found this,, Think the connection only uses 1 of the pins in the sensor..
SO the sensors I am seeing at parts store should work even though they have 3 pins..
Now I got to find a connector to work with it..

 

Can someone tell me when PIN the wire in the connector goes to?
There is 3 spots it could be and want to do it right the 1st time..
