They would keep the unit on the backside of pit wall like is done during the races.
The connections would be inside the cabin in My plan. The connectors are like an air hose but liquid/gas rated so they don’t leak so stray water would be minimal. Could be put on the right side of the cabin to keep clear of the driver and at some tracks they don’t run the right side Lexan and if they are it comes out easily.
