Obviously this modification has to be done at both ends of the cable. It would also be nice to attache a note to both ends for future techs. I've learn from personal experience from this.

Having to redo 30 to 40 cables one night at work and not knowing one of them had specially wiring really pissed me off. Couldn't tell you how many times I redid and redid that one cable. 1,000 foot run and really not knowing where on the casino floor it went because the floor lay out changed dozen of times over the years.
