The G4X WRXLink (7-9) Plug-in ECU has two CAN buses. These CAN buses exist to support aftermarket CAN devices.
CAN bus 1 uses a 5 pin connector and is labeled on the ECU as 'CAN 1/RS232'.
If using this connector for CAN ensure the cable being used doesn't have Serial wires connected as this can act as an aerial and prevent USB communications from working.
