Fan- only (Mosfet on Duet 3 Mini 5+?)

[Psike]

Good morning,
I have a problem connecting the fan to my old Mendel90.
Due to the old wiring, only the ground line (Fan-) leads to the old & new board.
Fan+ is supplied directly via 12V.
Is there a Mosfet on the Duet 3 Mini 5+ that switches to GND or do I have to rewire everything?

Thanks in advance
Lars

@psike all the OUT ports switch the ground pin. So connect the OUT- pin of whichever OUT port you select to the fan negative wire.
