When it comes to restoring classic cars like the 1967 Ford Mustang, understanding the wiring system is crucial. In this article, we will focus on the ignition coil wiring diagram for the 1967 Ford Mustang. The ignition coil is a critical component of the car’s engine, responsible for generating the spark that ignites the fuel mixture in the combustion chamber.
What is an Ignition Coil?
An ignition coil is an electrical component responsible for transforming the low voltage from the battery into the high voltage required to create the spark that ignites the fuel mixture in the engine’s cylinders. The ignition coil is powered by the car’s battery, and it generates a high voltage pulse that is delivered to the spark plugs through the distributor.
The primary winding of the ignition coil is connected to the car’s battery, while the secondary winding is connected to the distributor cap. When the distributor rotor spins, it makes contact with the ignition coil’s secondary wire, sending a high voltage pulse to the spark plugs in the correct firing order.

The wiring diagram for the 1967 Ford Mustang ignition coil consists of several components, including the battery, ignition switch, distributor, ignition coil, and spark plugs. The diagram illustrates how these components are connected and how the current flows through the system to create the spark that ignites the fuel mixture in the engine’s cylinders.
| Component | Wire Color | Connection |
|---|---|---|
| Battery | Red | Connected to the ignition switch |
| Ignition Switch | Red/Green | Connected to the ignition coil and the starter solenoid |
| Distributor | Black/Yellow, Green/Red, Black/White | Connected to the ignition coil and the spark plugs |
| Ignition Coil | Yellow/White, Green/Red | Connected to the battery, ignition switch, and distributor |
| Spark Plugs | Black/Red | Connected to the distributor |
The 1967 Ford Mustang ignition coil wiring diagram may seem complicated, but it is critical to understand how these components work together to ensure your car is running smoothly. It’s essential to check the wiring diagram for your specific make and model to ensure the wiring is correct.
Frequently Asked Questions About 1967 Ford Mustang Ignition Coil Wiring Diagram
1. What are the signs of a faulty ignition coil?
A faulty ignition coil can cause several symptoms, including difficulty starting the engine, engine misfires, stalling or hesitation during acceleration, and a decrease in fuel economy. If you notice any of these signs or your check engine light turns on, it’s crucial to have your car inspected by a qualified mechanic to identify the issue.
2. How can I test my ignition coil?
One way to test your ignition coil is to use a multimeter to measure the resistance of the primary and secondary windings. The primary winding should measure between 0.4 and 2 ohms, while the secondary winding should measure between 6,000 and 12,000 ohms. If the readings are outside of these ranges, your ignition coil may be faulty and should be replaced.
3. Can I replace my ignition coil myself?
Replacing an ignition coil can be a challenging task and should only be attempted by someone with experience in automotive repair. It involves disconnecting and reconnecting several wires and components and requires specific tools to complete the job correctly. It’s best to have a qualified mechanic replace your ignition coil to ensure the job is done correctly.
4. Why does my engine keep misfiring after replacing the ignition coil?
If your engine continues to misfire after replacing the ignition coil, there may be other issues with your car’s ignition system. It could be a faulty spark plug, distributor cap, or other components that need to be inspected and replaced. It’s essential to have your car checked by a qualified mechanic to identify the underlying issue.
5. How often should I replace my ignition coil?
Ignition coils typically last between 100,000 and 150,000 miles, depending on the make and model of your car. However, several factors can affect the lifespan of your ignition coil, including the frequency of use, driving conditions, and exposure to extreme temperatures. It’s essential to have your ignition coil inspected regularly and replaced when necessary to ensure your car is running smoothly.
