If no one comes up with a diagram, do you want to discuss it and figure it out for yourself?
It seems you would need 4 accessory ports:
1. Close clamshell (partial push of left button)
2. Raise bucket (complete push of left button)
3. Open bin door (middle button)
4. Lower bucket (right button)
Since the loader already comes with the cable and connector (not "loose" wires), you would need to splice in to these control wires...probably from inside the control box...and runs them over to the AIU.
