I FINALLY found the GROUND! It is on TOP of the HWH computer control box - the little screw was LOOSE! I tightened it down and now the solenoids are magnetized and you can definitely hear them click closed!
I still had the air hoses tied together in travel mode (not connected to the 6-pack manifold), now the problem is that when I pulled the air hoses off I failed to mark them or strap the driver/passenger sides together! So now I get to go through the motions of 16 different possible combinations of the hoses to get them correct.
Air will exhaust out the bottom of the manifold so LOWER should not be an issue.
RAISE and TRAVEL mode will be an issue as I have to figure out:
1) which hose goes to the PASSENGER side of the manifold (one for the connector closest to the FRONT of the coach)
2) which hose goes to the PASSENGER side of the manifold (one for the connector closest to the HWH bay)
3) which hose goes to the DRIVER side of the manifold (one for the connector closest to the FRONT of the coach)
4) which hose goes to the DRIVER side of the manifold (one for the connector closest to the HWH bay)
I think that is correct.
Then I will have to make sure my solenoids are going to the correct 12-volt Packard connector for each air bag/side/raise
