Ecu or amp under driver seat

Maybe on the sticker on the back of the driver door frame, or on the underside of the hood. My friend had an se-5 model and i thi k the only difference was some speed stripes on the side and different wheels. But its possible that abs was a part of it too, or it was just an option.

The sensor is in the center section of the diff. Mounted up high on the third member.
