Alert! A $10 discount is available when purchasing with a conversion kit or harness modification kit.
This interface board is for 1996 and later Subaru OBDII engines to eliminate 7 common fault codes. Some codes may still be present but none of those are the cause of runability issues. Comes with a list by name of the connections to the ECU. If it is ordered with our harness modification kit, the instructions there have a pinout specific to your year and model.
Now with built-in LED for check engine light!
