Update to this problem, I finally got my assembly manual and started picking at this problem. Come to find out my "Oil Temp Gauge" does not work because the oil temp sending unit is connected to the wrong gauge, the "Engine Temp Guage"! So the problem is not whether or not my "Oil Temp Gauge" works, which when I hook it up correctly I hope it works. It looks like my "Engine Temp sending unit" is not wired up or does not work.
I need to take my dash apart, Arrrgh, (that is going to be a long day) and straighten this mess out. And to think I have been watching my Engine Temp Gauge as if it were my oil temp gauge, knowing it was the oil temp I was monitoring and not realizing it was on the wrong gauge. Geesh, even I didn't understand that sentence.
I have looked through the assembly manual but can not find where the engine temp sensor is located. Any clues as to where to start looking would help out a lot.

The oil pressure sending unit's resistance goes up as pressure goes up, therefore if you ground the gauge lead at the sending unit the reading should go to zero.

I did this and the needle pegged to the left, not to zero.
