Oh, you're good. The ARB will come with a solenoid. Plumb it and lock em up.
So just curious, can you leave the air compressor activated during a run for extended lengths of time? Is the air evacuated through the vent or does it just keep the line pressurized to the vacuum diaphragm? I would have liked to had a backup air supply from the extreme air in case the ARB compressor fails which did happen to me making for an exciting trip getting out of an area we were in.
