10.0 Birds and Bees (Plugs vs. Jacks)
The EIA/TIA specifies an RJ-45 (ISO 8877) connector for Unshielded
Twisted Pair (UTP) cable. The plug is the male component crimped
on the end of the cable while the jack is the female component in
a wall plate or patch panel, etc. Here is the pin numbering to
answer the question, where is pin one?
Plug Jack
(Looking at connector (Looking at cavity
end with the cable in the wall)

12.2 Ethernet 10Base-T Crossover patch cord;
This cable can be used to cascade hubs, or for connecting
two Ethernet stations back-to-back without a hub (ideal for
two station Doom!) Note pin numbering in item 10.0 above.
RJ45 Plug 1 Tx+ -------------- Rx+ 3 RJ45 Plug
2 Tx- -------------- Rx- 6
3 Rx+ -------------- Tx+ 1
6 Rx- -------------- Tx- 2
