Fitting procedure
1. Most crimping pliers have two pairs of blades, one pair on one side to strip the wires and another pair on the other side to cut the wires. If the pliers do
not allow you to cut the cable sheath, you should use a blade and cut the sheath with it, removing a length of about three centimetres. Be especially
careful not to cut or scratch the wires inside the sheath; once cut, most sheaths break if they are folded or pulled.
2.
When you have removed the sheath, you will have four pairs of wires, twisted together two by two and of different colours. Untwist the wire pairs so
you have 8 separate wires, but make sure you mark them if they are not of different colours (in some cables, the white/colour wires are completely
white).
3.
Spread the wires out into a fan, in the order in which you need to crimp them from left to right. The cable configuration is illustrated in Table 1 and
Figure A.

4. Hold the wires tightly between two fingers and flatten them so that they are side by side, then straighten them by pulling them taut with your fingers
to remove slight curves caused by the previous twisting. Make sure they stay in the correct order.
5.
Continuing to hold them taut, trim the excess by 2 centimetres, so that they are all the same length.
