There are a few back there i'd just like to ID them all so I can then check to see if they are functioning correctly.
I replaced one for the low pressure air alarm, was leaking. I have one that activates when brake pedal is pushed but always is putting out like 2-3 volts even when off so im replacing that, and also high idle doesnt work so i'd like to know which one is for the park brake.
A diagram or schematic labeling what they are would be awesome.
