oil pressure sending unit location

Please tell me where the oil pressue sending unit is located on a 1995 bonneville. Thanks

What size engine does the car have in it? On most engines the Oil pressures sending unit is located just above the oil filter.

I found it . thanks It was leaking so bad I couldn't have missed it. I replaced the water pump a week ago and must have broked the plastic end of the oil pressure sending unit/oil level sending unit off when I lowered the power steering pump.
