Personally I would avoid disconnecting the cable from the socket as advised in this step, one should be able to proceed simply by carefully lifting the cable free from the adhesive holding it on to the optical drive.
Like others here, I followed Step 6 as per the guide and ended up with no Bluetooth or iSight camera, due to somehow damaging the connector and/or socket, despite taking the utmost care. It is possible to carefully slip the old drive out, and a new drive in, with the cable connector in situ (at least that was the case on my Late 2008 MacBook Pro).
