Where is the oil sending unit on your 1999 Chrysler cirrus?

On a 1999 Chrysler Cirrus, the oil pressure sending unit is located on the bottom of the engine block, near the oil filter. It's a relatively small unit and may be difficult to access without removing some undercarriage components. You'll likely need to get underneath the car to see it clearly. A shop manual or online diagrams specific to the 1999 Cirrus's engine (either the 2.5L or 2.7L V6) will give the best visual aid to pinpoint its exact location.
