I'm not so sure that's applicable here.  There is a rather large
number of cables involved here, after all.  We won't get anywhere by
exchanging the problem of connecting the right connector to the right
jack for the problem of connecting the right connector to the right
cable!

That's OK.  There are quite a few buildings out there where those
nice, safe, ``work in only one way'' electricity sockets have been
wired the wrong way around.  And that's done by ``professionals''!
