It is possible the 05DBW method is used for these, but I would have thought CAN was more likely. Give the other Subaru hookup methods a go.
If it's not CAN, you will need to connect the green test mode connectors. There may be more than one set; make sure the fans cycle when the ignition is turned on after connected the test mode connectors.
If that doesn't work, sight the ECU and perhaps even post a photo of outside and inside.
