66 Mustang Ignition Switch Wiring Diagram

The 1966 Ford Mustang is an iconic car that is loved by many classic car enthusiasts. One of the most important components of the Mustang is the ignition switch, which is responsible for starting the car and turning on the electrical systems. In this journal article, we will provide a detailed overview of the 66 Mustang ignition switch wiring diagram.

What is an Ignition Switch?

An ignition switch is a device that is used to start the engine of a vehicle. It is located on the steering column or dashboard of the car and is usually turned with a key to activate the starter and the electrical systems of the vehicle. The ignition switch is also responsible for connecting the battery to the starter motor and other components of the car that require electrical power.

On a 66 Mustang, the ignition switch is located on the steering column and is connected to the wiring harness of the car. It is a crucial part of the electrical system and must be wired correctly to ensure proper operation of the vehicle.

Wiring Diagram Overview

The 66 Mustang ignition switch wiring diagram consists of several components, including the ignition switch itself, the ignition resistor wire, and the ignition starter wire. There are also several other wires that connect to the ignition switch, including the accessory wire, the horn wire, and the turn signal wires.

The wiring diagram is divided into several sections, each of which represents a different part of the ignition system. The first section shows the ignition switch and the wires that connect to it. The second section shows the ignition resistor wire, which is used to limit the current to the ignition coil. The third section shows the ignition starter wire, which is used to connect the ignition switch to the starter solenoid.

Section 1: Ignition Switch Wiring

The first section of the wiring diagram shows the ignition switch and the wires that connect to it. The ignition switch has several terminals that are used to connect it to the wiring harness of the car. These terminals are labeled with letters, such as A, B, C, etc.

The A terminal is connected to the battery, while the B terminal is connected to the accessory wire. The C terminal is connected to the coil, while the S terminal is connected to the starter solenoid. There is also a T terminal, which is used for the tachometer.

The section also shows the wire colors for each of the terminals. For example, the A terminal is connected to a red wire, while the B terminal is connected to a green wire. The section also shows how the wires are connected to the ignition switch, using a series of arrows and diagrams.

Section 2: Ignition Resistor Wire

The second section of the wiring diagram shows the ignition resistor wire, which is used to limit the current to the ignition coil. The ignition resistor wire is a pink wire that runs from the ignition switch to the ignition coil. It is connected to the C terminal of the ignition switch.

The purpose of the ignition resistor wire is to prevent damage to the ignition coil by limiting the amount of current that flows through it. When the ignition switch is turned on, the current flows through the ignition resistor wire and into the ignition coil, which then produces a spark to ignite the fuel in the engine.

Section 3: Ignition Starter Wire

The third section of the wiring diagram shows the ignition starter wire, which is used to connect the ignition switch to the starter solenoid. The ignition starter wire is a red wire that runs from the ignition switch to the starter solenoid. It is connected to the S terminal of the ignition switch.

The purpose of the ignition starter wire is to activate the starter solenoid when the ignition switch is turned to the “Start” position. When this happens, the starter solenoid engages the starter motor, which then turns the engine over and starts the car.

FAQ

Q: Why is the ignition switch wiring diagram important?

The ignition switch wiring diagram is important because it shows how the ignition switch is connected to the rest of the electrical system of the car. Proper wiring is crucial to ensure that the ignition switch functions correctly and that the electrical systems of the car operate as they should.

Q: What happens if the ignition switch wiring is incorrect?

If the ignition switch wiring is incorrect, the car may not start or may experience other electrical problems. An incorrect wiring connection can cause damage to the ignition switch or other components of the electrical system, which can be expensive to repair or replace.

Q: Can I wire the ignition switch myself?

Wiring the ignition switch yourself is not recommended unless you have experience with automotive electrical systems. It is best to have a professional mechanic or electrician wire the ignition switch to ensure that it is done correctly.

Q: How can I find a wiring diagram for my 66 Mustang?

You can find a wiring diagram for your 66 Mustang in a repair manual or online. There are several websites that offer wiring diagrams for classic cars, including the 66 Mustang. It is important to make sure that the wiring diagram you use is specific to your year and model of Mustang.

Conclusion

The 66 Mustang ignition switch wiring diagram is a crucial component of the electrical system of the car. It shows how the ignition switch is connected to the rest of the electrical components and must be wired correctly to ensure proper operation of the vehicle. By following the wiring diagram and consulting with a professional mechanic or electrician, you can ensure that your 66 Mustang starts and runs smoothly.
