Where is the fuel pump relay on a 2003 Ford Mustang GT?

Location of the Fuel Pump Relay on a 2003 Ford Mustang GT
The fuel pump relay on a 2003 Ford Mustang GT is located in the Constant Control Relay Module (CCRM), which is under the hood in the engine compartment. It can be identified by its appearance, and it is typically found near the computer inside the passenger kick panel.
It’s important to note that the fuel pump relay may not be located in the trunk near the inertia switch, as one might assume. Instead, it is housed within the CCRM, as mentioned above.
