Follow my thread here for info on which bus it is. If it’s not steer ready tho (and thus you don’t have the engage button on the pillar), you won’t get far steering it I don’t think, but reading the WAS might be do-able: Steering a '22 MF 6718S over CANBUS
Not sure what speed you’re connected to the Arduino for the serial monitor at, but it should 115200
