Sata hd install issue

[ljb860ljb]

had my hd crap out and putchased a replacement. sata 250gb hitachi w/promise sata150 TX4 controller. Instructions say to "attach your system case's 2 or 4 pin LED cable to the LED connector on the sata150 tx series controller card". I don't have a clue what that is. Everyrthing else installs as directed but not spinning the drive, so can do nada as far as loading all my software, etc. any help would be appreicated.
