Turn signals not working? Suspect a faulty turn signal relay? Then you’re in the right place! This post is all about the wiring diagram of the 5-pin turn signal relay – from its meaning and function to troubleshooting. We’ll explain everything you need to know to tackle the problem yourself.
What Does “5-Pin Turn Signal Relay Wiring Diagram” Mean?
The term “5-Pin Turn Signal Relay Wiring Diagram” describes the graphical representation of the electrical connections of a turn signal relay with five terminals. It shows how the individual terminals of the relay are connected to other components of the turn signal circuit, such as the turn signal lamps, hazard lights, and turn signal switch. Understanding this wiring diagram is essential for anyone working with their car’s electrical system. A faulty relay can be not only annoying but also endanger road safety.
The 5-Pin Turn Signal Relay: The Heart of the Turn Signal Circuit
The turn signal relay is the central element of the turn signal circuit. It controls the rhythmic on-and-off switching of the turn signal lamps. A 5-pin relay, as the name suggests, has five terminals, each with a specific function. These are typically labeled with the symbols 49 (Positive), 49a (Output to the turn signals), 31 (Ground), C (Left turn signal indicator), and C2 (Right turn signal indicator). The relay itself is an electromagnetic switch activated by current flow. Dr. Klaus Müller, author of “Autoelektrik für Dummies,” explains: “The turn signal relay is a small but important component that significantly impacts road safety.”

Understanding the Wiring Diagram and Finding Faults
With the 5-pin turn signal relay wiring diagram, you can understand how the turn signal circuit works and systematically narrow down faults. First, you should understand the symbols in the wiring diagram. Then, you can use a multimeter to measure the voltages at the individual terminals of the relay. This helps determine whether the relay itself is faulty or if the problem lies elsewhere in the circuit. Typical faults include a corroded contact or a blown fuse.
Benefits of Understanding the Wiring Diagram
Understanding the turn signal relay wiring diagram allows you not only to find faults faster but also to save time and money. Instead of going straight to the workshop, you might be able to fix the problem yourself. Furthermore, you’ll gain a better understanding of how your car works and can make informed decisions about repairs.
Common Questions About the 5-Pin Turn Signal Relay
- Where can I find the turn signal relay in my car? The location of the turn signal relay varies depending on the vehicle model. It is usually located in the fuse box or near the steering wheel. You can find the exact location in your car’s owner’s manual.
- How do I test a 5-pin turn signal relay? You can test a turn signal relay with a multimeter by measuring the voltages at the individual terminals. Alternatively, you can replace the relay with a new one.
