Im setting up air suspension in a car and I am currently laying out all the wiring diagrams. I am stumped on one issue. I would like to have an all up/all down option on my setup, but cant figure out how to get it to behave appropriately. I cant figure out where to place the relay or diode, which is what I believe to be what I should use.
Basically, I can't figure out how to get the all up option without having the individual corner switches affect each solenoid the same way. I need to know if there is a simple isolation option for me. Any help?
