Attach the cable included in the kit to your second hard drive. In our case, we are using an SSD.

If your cable came with a small piece of black tape with rounded corners, you can install it over the hard drive cable connector to secure the connector to its socket on the hard drive. The piece of tape is not required and not installing it will have no adverse effects on your machine's performance.

Before attaching the cable to your hard drive make sure it has been properly folded along the dotted white lines. This will help the cable attach and stay in-place.
