Here is the thread that addresses the kit available for coaches older than 1995 - 1996. Mine is a 1995 and the suspension logic will release on low aux air pressure.

In post #7 is a link for the Prevost instruction for the upgrade and in post #16 is the price I was quoted.

I would be interested in hearing of the results of anyone that attempts to install this upgrade. I decided to keep my aux air system 'tight'.
