    What would happen if you disconnected each sensors 1 at a time to see what happens you may find it turns off and know that is the one?

    If you look closely at the harness attach to the pressure sensors and pressure switch ( LH under the dash just in front of the clutch pedal inside of the cab) there is a tag on each harness telling you their function.
    Sorry i don't have the diagram requested.
    Hope this can help.

    the parking brake sensor has a different connector from every other sensor it only goes in one place its about half way on the manifold on most models but you have to be careful when replacing this sensor because the way it plugs into the manifold is with a quickconnect fitting there is very little room to work and if you break the manifold or fitting then youre screwed just check connectors it should be next to the orange line and there is an etching on the manifold saying pbs you can't mix it up only one connector fits
