A further thought. Do it so the panel is easy to remove - you can get
Winter 'fast' connectors for the pneumatics, think about how the
electrics are connected as well to make it easy to do.

In my experience (and of others I know), these Winter pneumatic
connectors have a tendency to leak after a few years. I use standard
inline connectors along with short pieces of tubing which get replaced
every time I remove an instrument or the entire panel. Nearly as easy,
and no problem with leaks...
