This interface board is for 1996 and later Subaru OBDII engines to eliminate 7 common fault codes. The output voltage to the sensors is preset but is adjustable if needed to match your engine. 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.
