Where is the Generic Electronic Module located in a Ford Mustang GT?

There isn't a single component called a "Generic Electronic Module" in a Ford Mustang GT (or any other car, for that matter). Cars use many different electronic control modules (ECMs), each with a specific function. These modules are distributed throughout the vehicle.

To find a specific module, you'd need to know its function (e.g., Body Control Module, Powertrain Control Module, etc.) or its part number. Then, you could consult a wiring diagram or repair manual specific to your Mustang's year and model. These diagrams will show the location of each module.
