Introduction
The 1966 Mustang was a game-changer for the automotive industry. It was the car that started the pony car revolution and is still a popular choice for car enthusiasts today. When restoring a 1966 Mustang, it is important to get the headlight wiring diagram right. The headlight system includes the headlights, the headlight switch, and the wiring that connects them all together.
In this article, we will go over the different components of the headlight wiring diagram and how they all work together. We will also address some common questions that people have about the wiring diagram.
Components of the Headlight System
The headlight system of a 1966 Mustang consists of several different components. These include the headlights, the headlight switch, the dimmer switch, the wires that connect everything together, and the fuse box. Let’s take a closer look at each component.
Headlights
The headlights are the most critical component of the headlight system. Without them, you wouldn’t be able to see where you’re going at night. In the 1966 Mustang, the headlights are located on the front of the car and are powered by electricity.
Headlight Switch
The headlight switch is what turns the headlights on and off. It is usually located on the dashboard of the car and is connected to the wiring system. There are different positions on the headlight switch, such as low and high beam.
Dimmer Switch
The dimmer switch is what allows you to switch between low beam and high beam on the headlights. It is usually located on the steering column and is connected to the wiring system.
Wiring
The wiring system is what connects all the components of the headlight system together. The wires are usually made of copper and are wrapped in insulation. In the 1966 Mustang, there are different colors of wires that correspond to different components.
Fuse Box
The fuse box is what protects the headlight system from electrical overload. It contains fuses that are designed to break if too much electricity flows through them. This protects the wiring system from damage.
Wiring Diagram
Now that we understand the different components of the headlight system, let’s take a look at the wiring diagram. The wiring diagram for a 1966 Mustang headlight system is shown below:
