Where is the ECU on a 2005 Subaru WRX?

The ECU (Engine Control Unit) on a 2005 Subaru WRX is located under the dashboard on the driver's side. Specifically, it is positioned behind the kick panel, which is the plastic cover that protects the area near the footwell. To access it, you may need to remove the kick panel and possibly some additional wiring or components for better visibility.
