Hi ,, I just recieved the GM 3 bar MAP sensor ..

The sensor came with the plug and wiring harness but I dont know the wire positions of the 3 wires ,,, Its marked A,b,c but I need to know where the 5 volt ref ,ground and output signal wires corespont to ...

Also when I calibrate it the Cummins Im using doesnt have manifold vacum while running like a gas motor so do I set the low parameters on the calibration wizzard for 1 volt representing 0 PSI and 5 volts representing the max boost of 30 PSI ???

Thanks ..

Here is the data sheet for the MAP sensor.

0psi is going to be somewhere around 1.6 volts and 30 psi is around 4.9 volts.
