water line, electrical connector & lay reservoir down away from working area
preferably in a way where the washer fluid won't leak out while working on car).

next step refers to removing the air line. As long as there are no leaks in the
rear air springs and the suspension switch is turned off first, the rearend WILL
NOT sink down when removing the air line. Air won't go past the solenoids. When
removing the air line, you will get a quick small burst of air, but this is just
line pressure and is nothing to worry about.(the air pressure between the dryer
and solenoids)
