For Mustang enthusiasts, owning a 1968 Mustang is a dream come true. The classic design coupled with the powerful engine is a sight to behold. However, with time, the internal parts tend to deteriorate or malfunction, and the turn signal switch is no exception. This component is critical to ensure the Mustang’s safety while driving, and when it fails, it can be frustrating.
In this article, we’ll be discussing the 1968 Mustang turn signal switch wiring diagram to help you understand how it works, and troubleshoot issues that may arise. We’ll cover everything from the components of the turn signal switch to how to wire it correctly. So, let’s dive right in!
Understanding the 1968 Mustang Turn Signal Switch
The turn signal switch for a 1968 Mustang is an essential component that controls the turn signals, headlights, and brake lights. It is located on the steering column and is activated by moving the turn signal lever up or down. When the lever is moved up or down, it connects or disconnects the switch from the power source, which then signals the lights to turn on or off.
The switch is made up of several components, including the turn signal lever, the housing, the cancelling cam, and the wiring. Each of these components plays a crucial role in ensuring that the turn signal switch works correctly.
Components of the 1968 Mustang Turn Signal Switch
The turn signal switch for a 1968 Mustang comprises several components, each of which plays a critical role in its operation. Here’s an overview of each part:
| Component | Description |
|---|---|
| Turn signal lever | The lever that controls the turn signals, headlights, and brake lights |
| Housing | The casing that houses the components of the turn signal switch |
| Cancelling cam | The component that cancels the turn signal after a turn has been completed |
| Wiring | The wires that connect the switch to the car’s electrical system and the turn signal lights |
Now that we know the components let’s proceed to the wiring diagram.
1968 Mustang Turn Signal Switch Wiring Diagram
Understanding the wiring diagram for the turn signal switch can be challenging, but once you grasp the concept, it becomes straightforward. The wiring diagram is crucial in troubleshooting any issues that may arise with the turn signal switch. Here’s the wiring diagram for the 1968 Mustang turn signal switch:
Turning the Lights on
When the turn signal lever is moved down to the left or up to the right, the switch connects to the power source, and the left or right turn signal lights turn on. The power flows from the flasher to the turn signal switch and then through the wire to the lights. The blue wire from the flasher goes to the turn signal switch’s top right pin, while the green wire from the switch goes to the left turn signal light, and the yellow wire goes to the right turn signal light.
Turning the Headlights on
When the headlight switch is turned on, the power flows from the battery through the headlight switch and then to the turn signal switch. The white wire from the headlight switch connects to the top left pin of the turn signal switch, and the green wire from the switch connects to the headlights’ positive wire.
Brake Lights
When the brake pedal is pressed, the power flows from the battery to the brake light switch and then to the turn signal switch. The brake light switch is connected to the turn signal switch’s bottom left pin. When the brake pedal is pressed, it completes the circuit, and the power flows to the brake lights.
