Where does mini PCB fan plug in?

I followed the instructions, but didn't see where the mini PCB fan was installed.  Any help is much appreciated. Thank you!

The mini pcb fan has a positive red lead and a negative black lead that you need to extend with the supplied extension cord. Use the stripped lead in the extension cord as the negative ground. You wire this up to the 24V and ground screw terminals on the laser psu. This is the most right connector/terminal that has 4 screw terminals. The first (starting from left) is the 24 volts followed by ground.

Do I unplug the things that are in the spot or do I put the wires in there with the things plugged in?

You leave the existing wires in the 24Volt connection and add the pcb fan wires to it. Ensure you connect the minus of the fan (black) to the extension wire with a black stripe and to the minus 24V of the K40 laser power supply (similar the positive, red of the fan goes to the plus of 24V K40 power supply). There is an installation movie on the installation page for the drag chain, see https://awesometech1.wpengine.com/installing-gerbil-pro-pack/

good luck!
