Even if the pins are not in order, there is a color code, for both T568A and T568B wiring. Unable, therefore, to be wrong. Simply position the cable in front of the taking of color. Of course as it comes to wall outlets, it takes rigid cable, anyway much easier to position. With an impactor which cuts (type NGC2903 NGC Tool Impacting Krone / 110 + Chisel), installation is a breeze and a success every time. I prefer taken where the RJ45 socket is fixed, because it avoids that dislocates when pulling on the hip socket.
