There are jumpers located on the circuit board inside the case. These jumpers configure changes Subaru made between years.
The jumpers MUST be set before installing the adapter in the vehicle.

When the jumper consists of three pins in a row, correct selection is made by moving the jumper to the appropriate end of the three pins. |

When the jumper consists of four pins in a square, correct selection is made by positioning the two jumpers in either vertical or horizontal orientation. |
Information regarding the correct jumper position for the vehicle is printed on the PCB.
To access the jumpers, one end plate must be removed from the case and the PCB will slide out. Ensure the adapter is fully unplugged before removing the end plate.
