Fuel Pump Controller
Please send the complete body harness (at least from the dash to the headlights) from the WRX/STi including the ECU and fuel pump controller (FPC) that would be located in the trunk of the car. Leave what is physically on the engine untouched. If you have any questions, please ask before removing the harness.
