Air suspension dump valve

[giannid]

I think you might be better off just adding an old school dump valve in the cab. Messing around with the newer International stuff is always a pain in the ass and can cause the truck to throw a code. Nothing is simple anymore on these trucks. It's all designed to break and cost you a lot of money to fix. My dump valve on my international started bling on the switch. The dealer diagnosed it and said it had a solenoid and switch problem. Cost to fix was just shy of $800. Put a manual dump valve in and took the light out of the switch so it doesn't blink. :)
