I am installing an oil pressure gauge and need to locate the oil temp sending unit so that I can install a "T" fitting so that I can hook up my oil pressure sending unit. There appears to be (2) electrical connections coming from the oil filter area (one on top and one in the back)........ anyone know which one is the oil temp sensor?? TIA

I think it sends to the idiot lamp on the dash .. I don't think that is measuring the oil volume but rather oil pressure at some pre-determined pressure. IIRC it is like ~1.4 bar

Oil pressure and oil pressure switch, checking

Function of dynamic oil pressure warning system

Warning lamp, checking

With engine switched off and ignition on (terminal 15 on), oil pressure warning lamp will be lit (not for vehicles with Auto Check system).

Warning criteria

Engine switched off and oil pressure switch closed.

Coolant temperature less than 60C (140F), engine speed higher than 300 RPM and oil pressure switch open.

Coolant temperature greater than 60C (140F).

At engine speeds greater than 5000 RPM, an active oil warning won't be erased independent of oil pressure switch setting.

A Diagnostic Trouble Code (DTC) is recognized when oil pressure switch is open for more than 0.5 seconds at engine speeds greater than 1500 RPM. If condition occurs more than three times during a drive, warning will remain active even at engine speeds less than 1300 RPM.
