I'm not sure CPT Murphy would agree with you.  Was the problem that
the connectors were properly wired but plugged into the wrong jacks?
That is precisely the problem that Murphy analyzed and described a
fix for (key the connectors so they can't be inserted into the wrong
jacks).  By the way, I almost smoked a terminal recently by plugging
a "modular connector" into the wrong jack (one being used for an
entirely different purpose than the one near it).
