1968 Mustang Wiring Harness Diagram

Are you a proud owner of a 1968 Mustang? If you’re looking to restore your classic car to its original state, one of the most important things you’ll need is a wiring harness diagram. In this article, we’ll provide you with a comprehensive guide on the 1968 Mustang wiring harness diagram, including everything you need to know about the various components and how they work together.

The Wiring Harness Diagram

The wiring harness diagram is a map of all the electrical components in your 1968 Mustang. It shows how they are connected and where they are located in the car. By following this diagram, you can diagnose problems with your electrical system, and replace faulty components.

The diagram is broken down into sections that correspond to different areas of the car. These include the engine bay, the interior, and the exterior lighting. Each section is color-coded, making it easy to follow the wires and understand how they are connected.

Before you begin working on your electrical system, it’s important to have a good understanding of the wiring harness diagram. This will help you to identify which components are involved in a particular circuit, and which wires you need to test or replace.

The Components of the Wiring Harness Diagram

The wiring harness diagram includes a wide range of components, each of which has a specific function. These components include:

  • Battery: The battery is the heart of your electrical system. It provides power to all the other components in the car.
  • Alternator: The alternator recharges the battery and provides power to the rest of the electrical system when the engine is running.
  • Distributor: The distributor sends high-voltage electricity to each spark plug in the engine, igniting the fuel and air mixture.
  • Ignition Coil: The ignition coil amplifies the voltage from the distributor, sending a spark to the spark plugs.
  • Starter Solenoid: The starter solenoid engages the starter motor, which turns the engine over.
  • Wiper Motor: The wiper motor powers the windshield wipers and controls their speed.
  • Headlight Switch: The headlight switch turns on the headlights and controls their brightness.
  • Turn Signal Switch: The turn signal switch activates the turn signals on the car.
  • Brake Light Switch: The brake light switch activates the brake lights when the brake pedal is pressed.

The Engine Bay Wiring Diagram

The engine bay wiring diagram shows all the electrical components that are located in the engine bay of your 1968 Mustang. These include the battery, alternator, distributor, ignition coil, and starter solenoid.

The engine bay wiring diagram also shows the wiring for the various sensors and switches that are located in the engine bay. These include the oil pressure switch, temperature sensor, and vacuum advance.

There are a few key things to keep in mind when working on the engine bay wiring diagram. First, make sure that you disconnect the battery before working on any electrical components. Second, be careful when working around the distributor and ignition coil, as they generate high voltage electricity. Finally, be sure to follow the color-coded wires to ensure that you connect everything correctly.

The Interior Wiring Diagram

The interior wiring diagram shows all the electrical components that are located inside the car. These include the dashboard, seats, lights, and sound system.

The interior wiring diagram also shows the wiring for the various switches and controls that are located in the interior of the car. These include the headlight switch, turn signal switch, and windshield wiper switch.

When working on the interior wiring diagram, it’s important to be patient and take your time. The wiring in the interior of the car can be hard to reach, and it can be difficult to see what you’re doing. However, with some patience and careful attention to detail, you can successfully diagnose and repair any electrical problems in the interior of your 1968 Mustang.

The Exterior Lighting Wiring Diagram

The exterior lighting wiring diagram shows all the electrical components that are involved in the lighting system of your 1968 Mustang. These include the headlights, taillights, brake lights, and turn signals.

The exterior lighting wiring diagram also shows the wiring for the various sensors and switches that are located in the exterior lighting system. These include the headlight switch, turn signal switch, and brake light switch.

When working on the exterior lighting wiring diagram, it’s important to be careful and follow the color-coded wires. It can be difficult to see what you’re doing, especially if you’re working in low light conditions. However, with some patience and attention to detail, you can successfully diagnose and repair any electrical problems in the exterior lighting system of your 1968 Mustang.
