If you’re the owner of a 1968 Mustang, you know how important it is to ensure that all the components of your car work flawlessly to avoid any mishap on the road. The brake light system is one of the most important parts of a car that ensures safety, and understanding its wiring diagram is crucial to keep it functioning properly. In this article, we’ll walk you through everything you need to know about the 1968 Mustang brake light wiring diagram in simple, easy-to-understand language.
Understanding the Brake Light System
Before diving into the wiring diagram, let’s first understand how the brake light system works. The brake light system illuminates the brake lights at the rear of the car when you press the brake pedal, warning other drivers that you’re stopping or slowing down. The system consists of several components, including brake light switch, wiring harness, brake light bulbs, and fuses.
The Brake Light Switch
The brake light switch is usually mounted on the brake pedal arm and is responsible for turning on the brake lights when you press the brake pedal. When you press the brake pedal, the switch closes the circuit and sends a voltage signal to the brake light bulbs, illuminating them. If the brake light switch is faulty, the brake lights won’t turn on, and it could be dangerous on the road.
The Wiring Harness
The wiring harness is a set of wires that connect the brake light switch to the brake light bulbs. It’s essential to ensure that the wiring harness is properly connected and free from any damage or corrosion to avoid any electrical issues that could affect the brake light system’s performance.
The Brake Light Bulbs
The brake light bulbs are responsible for illuminating the brake lights when the brake pedal is pressed. They should be regularly checked and replaced if needed to ensure proper functioning of the system.
The Fuses
The fuses protect the brake light system from any electrical damage and should be checked regularly to ensure that they’re not blown. If a fuse is blown, it needs to be replaced immediately to avoid any issues with the brake light system.

Frequently Asked Questions
1. What should I do if my brake lights are not turning on?
If your brake lights are not turning on, the first thing you should check is the brake light switch. Ensure that it’s properly connected and not damaged. Also, check for any issues with the wiring harness or the brake light bulbs.
2. Can I use LED bulbs for my 1968 Mustang brake light system?
Yes, you can use LED bulbs for your 1968 Mustang brake light system. LED bulbs are more energy-efficient and have a longer lifespan than conventional bulbs, but make sure to use bulbs that are compatible with your car’s brake light system.
3. How do I replace a blown fuse in my brake light system?
The first step is to locate the fuse box, which is usually located under the dashboard on the driver’s side or in the engine compartment. Once you’ve located the fuse box, identify the fuse that’s blown and use a fuse puller to remove it. Replace the blown fuse with a new one of the same amperage rating and recheck the brake light system.
4. How often should I check my brake light system?
You should check the brake light system regularly, preferably every time you’re about to drive the car. It’s always better to identify any issues beforehand than to find out when it’s too late.
5. Can I repair the brake light switch myself?
While it’s possible to repair the brake light switch yourself, it’s recommended to get it replaced by a professional mechanic to avoid any potential safety hazards on the road.
By following the steps outlined in this article and regularly checking your brake light system, you can maintain a safe and reliable ride in your 1968 Mustang. If you’re not confident working on the system yourself, it’s always better to seek professional help to ensure everything is functioning correctly. Always prioritize safety when it comes to your car’s components, and you’ll enjoy many trouble-free miles behind the wheel!
