3 extra wires on 24 pin connector on PSU - what are they for?

I recently acquired an Antec CP-850 which was missing it's 24 pin plastic module (i.e. all the wires were just all over the place) after reconnecting all the wires into a new plastic connector I'm left over with 3 wires that I'm not sure what to do with.

One is a brown wire which I've read is a 3.3V Sense Wire and I've read (after a quick Google) that it's optional, so I'm happy to ignore this one.

One is a black and yellow cable, it's rather thin.
The other is a red and white cable, it's also thin.

I can't find anything helpful after Googling - I have hooked up my PSU to a couple of computers and it appears to be working fine without these 3 wires connected so I'm tempted to just ignore them (maybe wrap them in some insulation tape and tuck them away in the sleeve?).

Thanks in advance.
