Oil Pressure Sending Unit

I have decided that my oil pressure sending unit is bad on my 85 Corvette. I purchased a new one and have tried to put it in for about a week. I can not seem to find where the oil pressure sending unit is located. I have a digital readout dash and I have found all of the other sensors. I have found the oil temprature sending unit, which is near the oil filter.
Does anyone know where the oil pressure sending unit is located?
Thanks

I just joined and saw your post. the sendind unit is just below the distributor and closer to the wiper motor . Between the motor and the firewall. Go all way to back of engine and look down about 6". Youll find oil pressure and oil cutoff switch together . pressure switch is the bigger of the two.
