Where does this go? (LED Strip)

Just bought a new PSU to replace my old one and I notice none of the LED Strips work. So I went back and discovered a cable with no connector, I'm pretty sure this is the one causing the issue but there are only two connectors and yet three cables and swapping one out doesn't do anything. They are all just a standard 4-pin cable/connector.

As you can see, the three cables I'm holding up are all identical, yet the middle one has no connector. The left one goes from the LED control button to the PSU, the middle goes from the LED control button to nowhere and the right one goes from the my top LED strip to the LED control button. As far as I know, my old PSU didn't have any connectors available for the one lone cable as well.

Anyone know whats up?
