Air suspension dump valve

[allan82782]

I have an 08 international prostar that doesn't have an air suspension dump valve but it do have an sliding fifth wheel that doesn't need sliding. How do I convert the sliding fifth wheel air line to an air suspension dump valve while still using the sliding fifth wheel solenoid and switch in the dashboard in the cab. I recently purchased an leveling valve for the air suspension from the dealer to assist with the dumping of the air.
