I'm trying to find out as well. I read elsewhere you need something like this without the bracket: http://www.amazon.com/gp/product/B0056OB...
However I have NOT confirmed this.
I'm replacing my optical drive too. what exactly needs to be plugged into the SSD? I don't have the kit - as I am not sure one is required if I buy something like this: http://www.amazon.com/gp/product/B0056OB...
Can you please advise? Can I do it with this piece, or do I need to get the entire bracket kit?
