Default 2004 Concorde ECM/PCM Location

My mechanic has confirmed that I need a replacement ECM/PCM module, and basically told me I could save money by purchasing it from their supplier myself and replacing it myself.

That said, where can I find it and how do I remove it? I'm ignorant about most things car repair, but follow directions well.

The PCM engine control strategy prevents reduced idle speeds until after the engine operates for 320 km (200 miles). If the PCM is replaced after 320 km (200 miles) of usage, update the mileage and vehicle identification number (VIN) in the new PCM. Use the DRBIII® scan tool to change the mileage and VIN in the PCM. If this step is not done a diagnostic trouble code (DTC) may be set and SKIM must be done or car will not start if it is a SKIM equipped car. If a SKIM car you must do a secret key transfer also. Refer to the appropriate Powertrain Diagnostic Manual and the DRBIII® scan tool.

To avoid possible voltage spike damage to PCM, ignition key must be off, and the negative battery cable must be disconnected before unplugging the PCM connectors. Note radio programs.

Unbolt the washer bottle filler neck and reposition.
Disconnect the 4 PCM electrical connector.
Reposition wiring harness out of the way (NGC CONNECTORS).
Remove the 3 fasteners from PCM mounting (NGC MOUNTING).
Remove PCM (NGC CONTROLLER).
