Note: It's important that each pair is kept as a pair. 1a & 1b must be in the pair, and 2a & 2b must be together in another pair. (Just as the tables above show).

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

Pair Pins Common color
1 4 & 5 Blue
2 1 & 2
3 3 & 6 Orange
4 7 & 8

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