    Could someone please confirm if I have the wiring correct.

    The extruder fan get connected directly to either the 12v supply or onto the 2 pin connector on the ramps board?

    The printing blower fan gets connected to the connector D9?

    Cooling fans that should always be on should be wired to power directly. The import ramps has a notoriously poor connector (green plug) you want to limit what gets connected on the board side and keep everything possible (fans, LEds) on the power supply side.

    The print fan that is controlled by the software and is blowing on a print is wired to D9.
