The Six Pack is the group of six solenoid that are used by the HWH leveling system to adjust the air pressure in the bags when leveling. There is one in the front behind the headlights, on the drivers side and one or two sets depending on the year of coach (likely just one set on yours) in the engine compartment on the passengers side up close to where the firewall would be. They are an aluminum block with air passages inside, six solenoids, each about the size of a 35mm film case. There are two travel solenoids, two raise solenoids and two lower solenoids. During the early 1990's there were two sets of six packs in the rear. One set for the drive axle and one set for the tag axle.
