That's easy, on page 12 of your manual. Plug the hd led connector to ALED (IDE LED) Pin 7,8. There is no pin 2 but you have to count the missing space as pin #2. When you get you led light to work, please let me know if the light on yours is dim like mine, not as bright as I seem. Have you installed the raid ultility software, I reinstalled windows few time just to have it work but some remote files was not installed, does your have this problem?
