Hey DZZippy, I would be interested in the ECU if still available.

Hey DZZippy, Thank you for all your help, I have mapped out all the tag solenoid valve and could not come up with a link to the air leveling system just needed reassurance that I wasn't missing something. I had the air lose down to less then 1psi an hour and started the tag axle repair, tag works great but air lose is baffling. The only repair was to the lift chamber airlines and solenoid valve was replaced, no air to chambers when de-energized. Not real good at posting but giving it a gallant effort, by the way if anyone is interested I found the makers of the KIp solenoid valve and part numbers.

Hey DZZippy, I too am going through same issue as Ron, my question to you is how the Tag Axle is part of the air leveling system. I have replaced lift chamber solenoid valve and air lines to Tag, lifting slow but lifting,now losing air over night (all air)
