Basics of the 2011 Ford Fusion Headlight Wiring Diagram
The 2011 Ford Fusion headlight wiring diagram is relatively straightforward. There are two headlights on the vehicle, one on the driver’s side and one on the passenger’s side. Each headlight is connected to the car’s electrical system through a wiring harness that is connected to the headlight switch.
The headlight switch is located on the dashboard of the vehicle and is responsible for turning the headlights on and off. When the switch is turned on, a signal is sent to the wiring harness, which activates the headlights. The headlights are typically powered by the car’s battery, and the wiring harness is responsible for providing power to the headlights from the battery.
The wiring diagram for the 2011 Ford Fusion headlight system will typically include information about the wiring harness, the headlight switch, and the headlights themselves. The diagram will show you how the components are connected together and can be useful in diagnosing any issues that you may be experiencing.
For example, if you are experiencing an issue with one of the headlights not turning on, the wiring diagram can help you determine if the issue is with the wiring harness, the headlight switch, or the headlight itself. By using the wiring diagram, you can test the different components to determine where the issue lies.

Frequently Asked Questions
How do I test the headlight switch?
To test the headlight switch, you will need a multimeter. Set the multimeter to the resistance setting and remove the wiring harness from the back of the switch. Place one of the multimeter probes on the pin of the switch and the other on the ground. The multimeter should read zero resistance when the switch is turned on and infinite resistance when it is turned off.
How do I test the wiring harness?
To test the wiring harness, you will need a multimeter. Set the multimeter to the continuity setting and disconnect the wiring harness from the headlight. Place one of the multimeter probes on the wiring harness and the other on the headlight. The multimeter should read continuity, indicating that the wiring is intact.
