There are two holes on the left side of the oil pan and 2 sensors that go in them. One has two wires an is about 3 inches long. The other is short and has a single wire. Which goes in the front upper hole and which goes in the lower rear hole,

Thanks for the help, Herb

 

One is oil level sensor and the other is the sub zero sensor.

Sub-Zero is A-07 (page A) and is the most forward sensor

Oil level sensor is C-06

The Sub-Zero system never worked right. I'd remove the sub-zero tank. I think there was a TSB that said to keep the sub-zero pump unplugged
