Many classic car enthusiasts dream of owning a 68 Mustang. However, working on the electrical system can be a nightmare without a proper wiring diagram. In this article, we will provide a comprehensive guide on how to read and understand the 68 Mustang wiring diagram.
What is a Wiring Diagram?
A wiring diagram is a visual representation of the electrical circuitry present in a vehicle. It shows the connections between different electrical components and the path of electrical power flow. In short, it is like a road map that helps technicians troubleshoot and repair electrical problems in the vehicle.
As a beginner, reading a wiring diagram may seem daunting. However, with a basic understanding of the symbols and colors used, anyone can decipher the diagram with ease.
Color Codes Used in the Wiring Diagram
The colors used in the 68 Mustang wiring diagram have specific meanings. Here is what they indicate:
| Color | Meaning |
|---|---|
| Black | Ground |
| Blue | Alternator regulator circuit |
| Brown | Tail lights and license plate light circuit |
| Green | Right turn signal circuit |
| Red | Battery feed circuits and ignition switch circuits |
| White | Courtesy light circuit |
| Yellow | Left turn signal circuit |
Symbols Used in the Wiring Diagram
The symbols used in the 68 Mustang wiring diagram are universal and are used in most automotive wiring diagrams. Here are some of the common symbols and what they represent:
| Symbol | Meaning |
|---|---|
| Square | Component connector |
| Circle | Component |
| Diamond | System or power source |
| Rectangle with lines | Circuit breaker |
| Zigzag line | Resistor |
| Inverted triangle | Switch |
| Arrow | Flow of electrical current |
Understanding the Wiring Diagram
The 68 Mustang wiring diagram is comprised of many individual circuits. Each circuit is identified by a color code and a label. The labels indicate the function of the circuit.
For example, circuit 120 is labeled ‘Battery Feed’. This circuit supplies power to several other circuits such as the starter, ignition coil, and alternator. By following the path of the circuit, we can trace the power flow and identify any faults or defects.
Common Wiring Diagram Issues
When working on the electrical system of a 68 Mustang, common issues that may arise include blown fuses, faulty wires, and corroded connections. By referring to the wiring diagram, we can troubleshoot and solve these problems with ease.
Here are some common issues and their solutions:
Blown Fuses
If a fuse blows, it indicates an overload or a short circuit in the circuit. By referring to the wiring diagram, we can identify which circuit the fuse belongs to and check for any damaged wires or components.
Faulty Wires
If a wire is faulty, it can cause the circuit to malfunction. By using the wiring diagram, we can identify the wire and repair or replace it as necessary.
Corroded Connections
Corroded connections can cause poor electrical contact and result in a weak or intermittent signal. By referring to the wiring diagram, we can identify the affected circuit and clean or replace any corroded connectors.
