HWH 2000 Air Leveling System Problem

Yahoo Message Number: 91785
I have a 2006 Country Coach Inspire (with air brakes and without tag axle) that has the HWH 2000 Series Air Leveling System.

Short question first:

I have gone through my wiring diagrams in great detail. However, I cannot find any schematic showing the coach connections to the HWH leveling system. Does anyone have a schematic that shows these connections that they might share with me?
Long question - has anyone had the following type of problem with their HWH air leveling: The air leveling system operates very intermittently. The failure mode is always the same: After parking the coach and setting the parking brake, when the AIR button is pressed to start the leveling process, the NOT IN PARK/BRAKE light will illuminate and the coach will not level. All other functions will operate normally: I can dump the air or raise the coach and the coach will go into TRAVEL mode without any problems. Sometimes it will operate normally (the AIR light comes on and the coach will level) - other times it will not go into leveling mode no matter how many times I try. I have tried connecting a wire with a switch in the line (so I can by-pass the Park Brake switch and ground the input manually) directly from ground to the Park Brake Switch wire into the HWH control box (HWH wire #9000). The operation is still intermittent. I have tried dumping the air before leveling and tried without dumping the air before leveling - still intermittent.
If anyone has had this problem - could you share what the solution was?
I have placed a call to HWH and am supposed to be in the queue to get a call from technical service about my problem but HWH says it will be 3-4 weeks before I can expect a call back from one of their technicians. I would at least like to verify that all inputs to the system are proper before they call back (reason for needing coach to system wiring diagram).

I don't think so since I can dump the air and the coach will sit completely down - then if I select Travel Mode, the coach will return to the correct ride height all the way around. It isn't that the air bags won't level the coach, it is the fact that the control box will not go into the leveling mode. If I ever get the AIR light to illuminate (the NOT IN PARK/BRAKE light NOT on), the coach will level either automatically or manually.

Could be the park brake switch is failing. Or the unit does not think the trans is in neutral

I don't have the air leveling system I have the Power Gear hydraulic system. However, I did have a similar issue and thought it was the park brake switch. As it turned out to be only the ground was not good. After attaching a new ground to the park switch everything went back to normal, Just a thought.
