The ECU is actually called the PCM (Powertrain Control Module); however, the "brains" are located on the driver's side of the neon between the radiator and the transmission. It sits down near the bottom of the radiator. Be careful not to hit the transmission line going into the radiator because the radiator is made of plastic and that fitting is metal. Mine sheared at the radiator and you just have to replace the entire radiator. You will know the ecu as there are two receptacles with a multiwire plug in the top of the unit. These wires go to various sensors all over the vehicle.
