When it comes to restoring classic cars, the 1968 Mustang is a fan favorite. One of the standout features of this car is the fog lights. If you’re looking to restore your Mustang’s fog lights to their original glory, you’ll need a wiring diagram to guide you. In this article, we’ll walk you through the fog light wiring diagram for the 1968 Mustang, including tips and FAQs to make sure your restoration project goes smoothly.
Why the 1968 Mustang Fog Lights are Important
The 1968 Mustang was the first year that fog lights were available as an option, making them a popular feature for Mustang enthusiasts. Fog lights are important for safety while driving in foggy, rainy, and other low-light conditions. They provide extra visibility and help prevent accidents. Plus, they give your Mustang that iconic look that makes it stand out on the road.
If your 1968 Mustang’s fog lights are not working, it may be time to replace or repair them. Knowing how the wiring works is crucial to getting them back up and running.
The 1968 Mustang Fog Light Wiring Diagram
Before we jump into the wiring diagram, it’s important to understand the basic components of the fog light system in the 1968 Mustang. The system consists of two fog lights, a relay, a fuse, a switch, and the wiring connecting them all together. Here’s how it works:
- The fog light switch is turned on
- The switch sends a signal to the relay
- The relay activates and sends power to the fog lights
Here’s a visual representation of the wiring diagram:
| Color | Function |
| Green w/ Red Stripe | Fog Light Feed (From Fuse Panel) |
| Yellow w/ Black Stripe | Fog Light Switch to Fog Light Relay to Fuse Block |
| Red w/ Blue Stripe | Fog Light Switch to Fog Light Relay to Fog Lights |
| White w/ Black Stripe | Fog Light Relay to Fog Lights |
| Black w/ Yellow Stripe | Fog Light Relay to Ground |
Now that we have a basic understanding of the wiring diagram, let’s dive into each component and how they work together.
The Fog Light Switch
The fog light switch is located on the Mustang’s dashboard, to the left of the steering wheel. When the switch is turned on, it sends a signal to the relay, which in turn activates the fog lights.
The switch has three positions: off, parking lights, and fog lights. When the switch is in the parking light position, the fog lights won’t turn on, even though the switch is on. This is a safety feature to prevent the fog lights from being left on accidentally.
The Relay
The relay is a crucial component of the fog light system. It’s what allows the fog lights to turn on and off when the switch is activated. Without the relay, the fog lights wouldn’t work at all.
When the switch is turned on, it sends a signal to the relay. The relay then activates and sends power to the fog lights. The relay also protects the system by preventing high voltage from damaging the fog lights when they’re turned off.
The Fuse
The fuse is an important safety feature in the fog light system. It’s designed to protect the circuit from damage caused by overloading or short circuits. If the circuit becomes overloaded, the fuse will blow and prevent damage to the rest of the system.
The fuse for the fog lights is located in the main fuse box, which is located under the dashboard on the driver’s side of the Mustang.
The Fog Lights
The fog lights themselves are the final component in the system. They’re mounted on the front bumper of the Mustang and provide extra visibility in low-light conditions.
The fog lights are connected to the relay by two wires, one positive and one negative. When the relay sends power to the fog lights, they turn on and provide extra visibility.
FAQs
What size fuse do I need for the fog lights?
The fuse for the fog lights in the 1968 Mustang should be a 14-amp fuse.
Where can I find replacement fog light parts?
If you need to replace any parts of your 1968 Mustang’s fog light system, there are many places to find them. Online retailers and Mustang specialty shops are good places to start. You can also find used parts on auction sites like eBay.
Do I need to use original parts to restore my Mustang’s fog lights?
While using original parts can help maintain the authenticity of your Mustang’s fog lights, it’s not necessary. Many replacement parts are available that will work just as well as the original parts, and they may be more affordable and easier to find.
Can I install fog lights on a Mustang that didn’t originally come with them?
Yes, it’s possible to install fog lights on a Mustang that didn’t originally come with them. However, you’ll need to make sure the wiring is compatible and that the switch and relay are installed correctly. It’s also important to check the local laws to make sure the installation is legal.
Can I install LED fog lights on my Mustang?
Yes, it’s possible to install LED fog lights on a 1968 Mustang. However, you’ll need to make sure they’re designed to work with the Mustang’s electrical system and that they meet local laws and regulations.
Conclusion
The fog lights on the 1968 Mustang are an iconic feature that many enthusiasts want to restore to their original glory. Understanding the fog light wiring diagram is crucial to ensuring that the restoration project goes smoothly. By following this guide and the included FAQs, you’ll be well on your way to restoring your Mustang’s fog lights to their former glory.
