The turbos, (and others) have 2 oil pressure senders, the high pressure one
is on the oil filter casting, the low pressure one is on the end of the head.
They both wire to the oil pressure "computer" hidden behind the speedo, that
sounds the buzzer when oil pressure is low, and rpms are about 2k. The
"computer" (not realy) also gets a speed cue from the "W" terminal of the
alternator, also known as the tach terminal. The one on the head ensurs that
the cam is getting enough oil, and the high press. one shouts if the main
pump output drops.
