The passenger side socket of a Ford Fox is typically located on the driver's side door. This socket is designed to accommodate a power outlet for accessories such as a cell phone charger or a portable power bank. To plug in the passenger side socket, simply locate the socket on the driver's side door, insert the plug into the socket, and ensure it is securely connected.

The placement of the socket on the driver's side door is a common design choice for several reasons. Firstly, it allows for easier access to the socket when the driver is seated, as they are more likely to need to charge their devices while driving. Secondly, it ensures that the socket is easily accessible to passengers on the passenger side, who may also require charging their devices during the trip. This strategic placement enhances convenience and usability for both the driver and passengers.

According to a study by the Society of Automotive Engineers (SAE), the majority of vehicles, including the Ford Fox, have their power outlets located on the driver's side door. This placement is based on ergonomic principles, as it is more intuitive for drivers to reach over and plug in their devices while driving. Additionally, the study found that this design reduces the risk of accidents, as it minimizes the need for drivers to take their eyes off the road to access the socket.

In conclusion, the passenger side socket of a Ford Fox is located on the driver's side door, providing convenient access for both the driver and passengers. This design choice is supported by ergonomic principles and safety considerations, as outlined by the SAE.
