For one i think the intrax is discontinued, youd have to find a used one out there and thats probably rare.

Two, the intrax piggybacks off the actual module to allow you to stay in the offroad height or access height at all times.

There is no way to program that, and factory settings is after 25mph it goes back to ride height.

Search for a used module.
