If your compressor is in good shape, you can jumper out two pins and then use it like a normal compressor for tire inflation, lockers, etc.. By getting creative with the pins, you can then use one of the EAS buttons to activate the compressor as needed. You'll need to install a couple of couplers for connecting hoses for inflation. Can't recall the pin numbers on the EAS ecu, maybe someone else can chime in. If you're planning on using it for tire inflation, you'll want to run for a bit, then cool for a few mintures in order to extend the life of the compressor.
