RGB light strip 5,1 Mac Pro

I have a mid 2010 Mac Pro 5,1. I want to put a RGB light strip in it,

I read an article that said this: “The factory fans of the Mac Pro are quite decent, if you [only want to add RGB to your Mac], you can install an LED strip that has a SATA connection and RF remote control to change the color of the strip. You can get power from the SATA cable of the second optical drive bay, and if you happen to have both bays used you can use a Y cable”.

So I bought this RGB kit from amazon: LED RGB PC Light Strip - Speclux Computer Magnetic Addressable LED Strip Kit And this Y cable StarTech.com 6in Latching SATA Power Y Splitter Cable Adapter - M / F

The MOBO SATA connector on the Y cable I bought is not quite the right fit. I attached some pictures of what I mean. I would think the answer to this question is simple - lol !!

What cable do I need to get to set this up properly and where, thanks Nick.
