What type of power control module do I need and where is it located?

Hello,

The Powertrain Control Module (PCM) is mounted through cowl panel.
You will have to access it from under the hood (see diagram below).

Yes, you can simply get the number from the PCM itself. Another option would be to call your local Ford dealer and provide them with the VIN. They will be able to look up and let you know which part number is your PCM.
Also, the replacement PCM will need to be programmed to your vehicle, using a special scan tool.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
