Can I use 3 hard drives in the XPS 8920?

I have an XPS 8920 that I added a second hard drive to no problem.  I want to add a third drive which is a solid state drive, and there are 3 bays for hard drives, but I don't see a third data cable.  Do I need to get a cable that will piggy back off the other ones?  

Please Help !
Thanks !

I didn't find the right solution from the internet.
