I could work last week quite a bit on my MB, tackeld the wing/fuse connections. Without any previous experience working with quick air disconnects, the result was not bad.
In stead of having separate "blocks" for both air and electrics like in the beginning of this thread, I used ONE former to mount both units upon, hopefully this gives more resistance against movement of fuse and wing parts when air pressure is on.
For electric connections I used the Sub-D that is a 90 degree version, so inside the fuse it nicely looks downward in order for the leads to be routed under the tanks.
