Accuair redux

[Jimbabwe]

I've been running Ridetech's Ride Pro analog system on my truck for the past two years and I'm thinking of switching to Accuair E-Level because the manual switch thing is getting a bit tiresome trying to get the truck level after laying out. The pressures never seem to be the same for a given height, and I frequently notice one side (never the same) will actually increase in height and pressure after setting it to level on a flat surface and driving just a short amount of time.
I was told that Accuair sells a harness to use their E-Level (controller and height sensors) with my existing system, and was wondering if anyone has done this. It's probably not worth the effort to try and combine the two setups to save money, and I could sell the RidePro stuff to fund the Accuair purchase a bit.
Also, I searched the forum and was wondering if anyone has links to any more detailed Accuair ride height sensor installs.
Thanks.
