There are 4 split wires which consist of one normal wire and one wire which is a smaller gauge. However, I know how these relate to the connector. For example 24P-2 is repeated in the pinout diagram in the 18pin connector because that is where the head, where the split wires meet, is connected. The smaller gauge wire is connected to the corresponding number ending with s i.e. in this case +3V3s is where the smaller gauge wire is connected.
K, thanks guys... I will follow the pin out diagram and let you know. I have also contacted corsair to see if they can shed any light, but I trust what you are saying i.e. my board won't blow-up is true... I will keep you informed.
