Folks, how does one know the specific valve (Selenoid) block that controls the inlet and outlet air supply to the back suspensions.Have traced why the back suspension is always going down and now suspect its the valve block, but which of the selenoid valve controls it I cant say. Please someone help with it.

the ports are numbered on the EAS box,

1-Left Rear
2-Right Rear.

If you have a leak in the valve block, rebuild the entire thing.
