Hdd led not working?

[Gravite]

I own the centurion 5 case but i never see the HDD led on. I plugged the HDD.Led line onto the motherboard which was the HD 2 pin F Panel slot but i still dont see any led... Just wondering whats MSG? is a slot above my HD slot.
Heres an example:

Hmmm, have you tried turning the HDD led line plug the other way round, so the "HDD LED" sign would be facing the other way.

Oh thx lol that worked... Never knew that would be the problem because all the other once like power switch,reset switch...etc are facing the other direction and they all works but except this one... So should i switch everything facing the same direction as the HDD led or just leave as it?
