The connector you are looking for should be coming from the power supply, not the SATA data ports on the motherboard.

With a SATA to Molex splitter like this one (https://www.amazon.com/StarTech-com-LP4SATAFM12-12-Inch-Molex-Adapter/dp/B0014BL9PE/) you can also power the coin door light mentioned in your other post.  (Mfr. webpage here (https://www.startech.com/Cables/Computer-Power/Internal/LP4-to-SATA-15-pin-Power-Adapter-with-2-Additional-LP4~LP4SATAFM2L) if you want more details)

You may want to swap the coin door incandescent bulb for an LED -- longer life, lower current draw.

Look at the cables coming from the power supply -- there will be either Molex or SATA power connectors to power hard drives, fans, etc.

Find a SATA power cable with a connector like this one coming from your computer's power supply.

The LED power chain looks like this:

Power supply SATA power cable --- SATA to Molex splitter (linked above) --- Molex cable in OP (between the trackball and USB cable in the pic below) --- Ultimate I/O board.

So it's mater of joining the SATA cable to the end of the Molex, as simple as that?

Coming out of the power supply is a SATA power cable like this.

(https://sgcdn.startech.com/005329/media/products/gallery_large/PYOLP42SATA.D.jpg)

Connect that to the left side of this splitter cable.

(https://sgcdn.startech.com/005329/media/products/gallery_large/LP4SATAFM2L.Main.jpg)

Splice either the 5v or 12v wires from the upper right connector to the coin door lights.

Connect the splitter's bottom right Molex to the Ultimate I/O LED power cable. (center top)

(http://www.ultimarc.com/images/ipacuio_wired.jpg)

With that, you now have power to the coin door lights and LED power to the Ultimate I/O board.

Each RGB LED button will also need these 4 wires: + (operating voltage provided by the power chain above), Red ground channel, Green ground channel, and Blue ground channel.

I use one of these to power the same board and my marquee leds. https://www.monoprice.com/Product?p_id=2372&gclid=EAIaIQobChMIhva31ceo1QIVgrXACh1WAANNEAQYASABEgJAGPD_BwE

Plugs into a molex from the power supply.
