Wiring Conventions
For Ethernet connections, a twisted-pair cable must have two pairs of 
wires. Each wire pair is identified by two different colors. For example, one 
wire might be red and the other, red with white stripes. Also, an RJ-45 
connector must be attached to both ends of the cable.

Each wire pair must be attached to the RJ-45 connectors in a specific 
orientation. The following figure illustrates how the pins on an Ethernet 
RJ-45 connector are numbered. Be sure to hold the connectors in the same 
orientation when attaching the wires to the pins.
