Mac Mini installing second hard drive SSD

Mac Forum question SATA

I want to keep my original hard drive in the Mac Mini PLUS have the SSD for my main drive. Its very cool that there is no particular hardware order. (I didnt know this at first and had completely taken my Mac Mini apart.) When you turn the MINI updside down to get in, then my original hard drive is on the bottom. But closed up and sitting on gthe desk like it should the hard drive is on the top. My issue is I purchased a second SSD SATA cable. When I went to plug in the new SSD CABLE IT WANTED TO PLUG INTO THE EXACT SAME PORT AS THE ORIGINAL ONE. I FOUND OUT THERE ARE 2 CABLES but in discriptions I see people writing this cable is for TOP drive or bottom drive. Is that upside down or closed? Any clarification of which SATA cable I need would greatly be appreciated. Remember when the unit is closed, then the drive is on top. Another way of putting it is all I have to do to install the new drive now is to just slide the new drive in (studs attached).

With the botom it will be on top of existing drive. Close the unit up, turn it over and set it on desk and the new drive is on the bottom. Sorry for being so redundant I just want to be sure. Thanks.
