Just FYI, those cables with the red/yellow/black wires (the one called "PB" on current HDD) are all power cables.

The adjacent cable with the blue wire is your SATA cable. It cuts off in the pics, but follow to where it is plugged into motherboard (MB). Looks like there is an empty plug right next to it. Also, it's too blurry to read, but somewhere in that vacinity on the MB there will be tiny writing like "SATA 1" and "SATA 2".

Also, have you ever dealt with the "jumpers" on a HDD? That is to the right of the SATA port on HDD, the 4x2 or 5x2 pin arrangement thingy. I can't tell if two of the pins are covered with a tiny black piece of plastic or not. Anyway, you may or may not need to bother with it.

(The jumpers tell your computer whether to treat a HDD as a "master" or "slave". Usually they will be set in an "auto" configuration which let's your software decide. Just not always.)
