I just installed (a few weeks ago) the wireless one...
Control is wireless and works great. I installed mine using a relay for power vs. their recommendation of connecting to a 15A fuse in the junction block. Installed Firestone Ride Rite bags, but used the Airlift compressor.
And if purchased before 10/31, there is a $75.00 rebate on the compressor system. (And Amazon is an authorized retailer for the rebate.)
