Most Ford engine control modules are located in the engine compartment near the battery and power distribution center. Locate the module by lifting the hood and searching for a metal electronics enclosure with a large number of wires going to it.
Engine control modules often have multiple electrical connectors going to them and a heat-exchanging enclosure. Some Ford vehicles use many modules to handle the overall vehicle control.
Consult a professional or the shop repair manual to ensure it is the correct one. To reduce the risk of injury or damaging components, always disconnect the vehicle's ground from the battery before working with any control modules.
