Can anyone post up a pic of the pressure switch on the pm3? Thanks in advance.

I don't have a pressure switch specific picture, but it's visible in this PMIII exploded diagram I have.

Thanks, what number is it on there? My brand new rebuilt pm3 motor won't shut off so I am hoping to use the old switch from my core. It is currently blowing the cap off the master. I am assuming too much pressure is being built up.

#26 on there. If you're looking directly at the PMIII unit, it's physically located just to the right of the accumulator. You'll probably have to lean down to see it as it's tucked under there when the unit is installed in the car.
