Need help with air system(brakes/retracts)
 

Just need some help with my air system on my MB-339 'Macci. This is my first jet and air system (brakes and retracts) and it has been a learning process the whole way. I am not clear on how the air lines will be connected , not sure where to start. I am hoping for a visual diagram if it is possible. I am using 2 separate systems , one each for brakes and retracts and am using Jet-tronics valves. All ideas welcome. Thanks!
