Once the input side is connected and the module installed on the frame, the output side 12v + connection wire (yellow) can be run back into the case and connected to the V_Fan_A terminal.

Note again that only the positive side of the output terminals is connected. The 12v - output is not required.

Once again a Dupont female connector is used on both ends of the wire since it can be securely pushed onto the V_Fan pin.

You will need to remove the existing jumper that currently bridges the V_Fan pin to the VIN pin which provides the stock fans with 24v (or 5v).

Use tape, clips, or wrap to secure the wires coming and going from the buck converter to ensure they are held clear of the bed and won't easily be pulled loose. A disconnected wire would cause the fans to stop working.
