The only thing missing in this feast of information is how the
individual pins are numbered on the socket. I can find how they're
numbered on the cable, but not the socket.

With RJ45 the pin numbers on the socket match those of the plug (unlike
say the BT phone plug!). However, that is not usually particularly
useful information since the presentation of the IDC terminals will vary
in layout depending on both brand and type of socket. So you need to
follow the colour code on the particular socket.
