    Question 2003 pinout for A/F Gauge install???

    2003 WRX Sedan

    I've hooked up the A/F gauge, mounted it in the pod, routed the signal wire, and found the ECU. All I need now is the right wire to splice at the ECU. I've searched and searched, but can only find the 2002 pinout. My 2003 ECU doesn't look the same. Does anyone know which wire I should use?
