Note: It's important that each pair is kept as a pair. TX+ & TX- must be in the pair, and RX+ & RX- must together in another pair. (Just as the table above shows).

Just for your information, this is how the pairs are named:

Pair Pins Color according to TIA568A
1 4 & 5 Blue
2 3 & 6 Orange
3 1 & 2 Green
4 7 & 8 Brown

The + side of each pair is called the "tip" and the - side is called the "ring", a reference to old telephone connectors.
