Hey Eric, we don't carry any air over electric brake controllers but we can still help. The P2 part # 90885 that you referenced can still work as it was designed to activate electric trailer brakes. It uses an internal inertia sensor to determine how hard to apply the trailer brakes and wouldn't require any input from your air system. It actually doesn't "care" what type of vehicle brakes you have. Your Mack is a 12 volt system right?
