1968 Mustang Wiring Diagram for Light

Are you looking for the wiring diagram for the lights on your 1968 Mustang? Look no further! In this article, we will provide you with all the information you need to wire the lights on your classic car. Whether you are restoring an old Mustang or simply need to replace a faulty wire, this guide will help you get the job done.

Introduction

Before we get started, it’s important to understand the basics of the 1968 Mustang’s electrical system. The car’s lighting system is powered by a 12-volt battery and consists of a headlight switch, dimmer switch, turn signal switch, and various relays and fuses. The wiring for each part of the lighting system is color-coded and labeled, making it easy to identify and trace each wire.

In this guide, we will focus on the wiring diagram for the headlights, taillights, and brake lights. We will also provide answers to some frequently asked questions about Mustang wiring.

Headlight Wiring Diagram

The headlight wiring diagram for the 1968 Mustang is relatively simple. The headlight switch sends power to the headlights through two different circuits. The first circuit provides power to the low beams, while the second circuit provides power to the high beams. The wiring for each circuit is color-coded and labeled for easy identification.

The following table provides a breakdown of the colors and functions of each wire in the headlight circuit:

Wire Color Function
Yellow with red stripe Power from headlight switch to low beam headlights
Green with red stripe Power from headlight switch to high beam headlights
Black with yellow stripe Ground for low beam headlights
Black with white stripe Ground for high beam headlights

When troubleshooting headlight issues, it’s important to check each wire for continuity and ensure that the correct amount of power is getting to each headlight.

Taillight Wiring Diagram

The taillight wiring diagram for the 1968 Mustang is slightly more complex than the headlight diagram, but it’s still relatively easy to follow. The wiring diagram includes the wiring for the taillights, reverse lights, and license plate light. Each circuit is color-coded and labeled for easy identification.

The following table provides a breakdown of the colors and functions of each wire in the taillight circuit:

Wire Color Function
Green with red stripe Power from headlight switch to taillights
Brown Power from backup light switch to reverse lights
Black with yellow stripe Ground for taillights and license plate light
Black with green stripe Ground for reverse lights

If you are troubleshooting taillight issues, it’s important to check each wire for continuity and ensure that the correct amount of power is getting to each light.

Brake Light Wiring Diagram

The brake light wiring diagram for the 1968 Mustang is relatively simple. When the brake pedal is depressed, power is sent from the brake light switch to the brake lights. Each circuit is color-coded and labeled for easy identification.

The following table provides a breakdown of the colors and functions of each wire in the brake light circuit:

Wire Color Function
Green with white stripe Power from brake light switch to brake lights
Black with red stripe Ground for brake lights

To troubleshoot brake light issues, it’s important to check each wire for continuity and ensure that the correct amount of power is getting to each light.

FAQ

Q: How do I know if a wire is faulty?

A: The easiest way to determine if a wire is faulty is to use a multimeter to test for continuity. Set the multimeter to the continuity testing mode and touch one lead to each end of a wire. If the multimeter beeps, that means the wire is continuous and is not faulty. If the multimeter does not beep, that means the wire is broken and needs to be replaced.

Q: Can I use automotive wire for my Mustang’s wiring?

A: Yes, you can use automotive wire for your Mustang’s wiring. However, it’s important to use the correct gauge of wire for each circuit to ensure that the correct amount of power is getting to each component. It’s also important to use wire that is rated for the voltage and amperage of your Mustang’s electrical system.

Q: Do I need to replace all the wiring in my Mustang?

A: It’s not necessary to replace all the wiring in your Mustang unless it is damaged or faulty. However, if you are restoring an old Mustang, it may be a good idea to replace the wiring harness to ensure that all the wiring is up to date and in good condition.

Q: How do I install a wiring harness in my Mustang?

A: Installing a wiring harness in your Mustang can be a daunting task, but it’s not impossible. The best way to do it is to follow the instructions that come with the wiring harness and take your time. It’s important to label all the wires as you remove the old harness so that you know where each wire goes when you install the new harness.

Q: Can I install LED bulbs in my Mustang?

A: Yes, you can install LED bulbs in your Mustang. However, it’s important to use bulbs that are designed for your Mustang’s electrical system to ensure that they work properly. It’s also important to check the wiring and fuses to make sure that they can handle the additional load of the LED bulbs.

Conclusion

Wiring the lights on your 1968 Mustang may seem like a daunting task, but with the right information and tools, it can be done relatively easily. By following the wiring diagrams and troubleshooting tips in this article, you can get your Mustang’s electrical system up and running in no time. Remember to take your time, label all the wires, and test each circuit for continuity to ensure that everything is working properly.
