DIG0-IN is pin 1 on the ACCY connection. This is where you would connect your FSK keying line for direct FSK with the K3. This should also be the same line for direct keying of PSK if you decide to use that. I think most folks will use DATA-A for PSK when using a soundcard program. PSK-D is there primarily for direct sending using your CW paddles without the need of an external computer.
