Every vehicle comes equipped with a turn signal system that alerts other drivers of your intent to change lanes or make a turn. The turn signal system is composed of several components, including the turn signal switch, flasher unit, and wiring harness. In this article, we will provide you with a step-by-step guide on how to read and understand a turn signal wiring diagram.
Understanding Turn Signal Wiring Diagram
A turn signal wiring diagram is a visual representation of the electrical connections and components involved in the turn signal system. It shows how the current flows through the system and how the different components are connected.
Reading and understanding a turn signal wiring diagram can be a daunting task, especially for beginners. However, with a little patience and some basic knowledge of electrical systems, anyone can learn how to interpret these diagrams.
The first step in understanding a turn signal wiring diagram is to familiarize yourself with the different symbols and codes used in the diagram. These symbols and codes represent different components and connections in the system.
The most common symbols and codes used in turn signal wiring diagrams are:
| Symbol or Code | Description |
|---|---|
| + | Positive (power) connection |
| – | Negative (ground) connection |
| # | Fuse |
| S | Switch |
| L | Lamp |
| X | Connector |

The Components of a Turn Signal Wiring Diagram
A turn signal wiring diagram typically includes the following components:
Turn Signal Switch
The turn signal switch is a lever on the steering column that controls the turn signals. When you move the lever up or down, it sends a signal to the flasher unit to turn on the corresponding turn signal lamps.
The turn signal switch also controls the hazard warning lamps, which are used to indicate a hazard or emergency situation.
Flasher Unit
The flasher unit is a small electronic device that controls the blinking rate of the turn signal lamps. It does this by interrupting the power to the lamps at a specific rate, usually around 60 flashes per minute.
The flasher unit also controls the hazard warning lamps, which blink at a faster rate to indicate a hazard or emergency situation.
Wiring Harness
The wiring harness is a network of wires that connects the different components of the turn signal system. It carries the electrical current from the battery to the switch, flasher unit, and lamps.
The wiring harness also includes connectors that allow you to easily disconnect and reconnect the different components of the system.
Bulbs or Lamps
The bulbs or lamps are the light sources that are used to indicate the turn signals. They are usually located in the front and rear of the vehicle and can be either incandescent or LED.
The bulbs or lamps also include the hazard warning lamps, which are usually located in the front and rear of the vehicle as well.
Ground Connection
The ground connection is an important part of the turn signal system. It provides a path for the electrical current to return to the battery after it has passed through the different components of the system.
Without a proper ground connection, the turn signals may not work or may work incorrectly.
Conclusion
A turn signal wiring diagram is an essential tool for anyone who wants to diagnose and fix problems with the turn signal system. By understanding the different components and connections in the system, you can easily troubleshoot and repair any issues that may arise.
Remember to always follow safety precautions when working with electrical systems and to use the appropriate tools and equipment.
