As anybody who owns one knows, an active 7 pin cable is so damned expensive and they get a lot of wear and tear in the field. On mine the glue that holds the little plastic stopper between the cable and the plastic seven pin plug came loose, so I reglued it and wrapped the whole cable and plug portion with a bunch of electrical tape to reinforce it, so all the flexxing doesn't mess with the connection ever again. Wish I had thought about it before it came loose, but hopefully all is well now.
One more tip for the day: I went out and bought some velcro at the sewing store and attatched it to my D8 and AD20, so that they'll stick together in my fanny pack and stay put.
Peace!
