Attaching The Hard Drive - OWC Mercury Elite-AL Pro Owner's Manual

5. Take your 3.5" SATA hard drive and set it into the drive enclo-
sure. You need to attach the power cable (the red, black, and
yellow cable) to the SATA hard drive, and also connect the SATA
cable to the hard drive. Make certain that you do not pinch the
red and black LED cable on the left side in this picture - make
sure it's free from being caught underneath the drive.
6. Once you have the cables attached, lower the hard drive down
into the enclosure, until it is flat on the mounting rails. Make sure
that the cables you just attached to the drive lay down flat, to aid
in the last step when you slide on the top cover.
