  • Green: Green wires are used to indicate chassis ground wires.

  • Yellow: Yellow wires are used to indicate lighting circuits.



Color-Coded Labels On Car Wiring Diagrams



In addition to the colour coding, car wiring diagrams will also have labels that tell you what each wire does. These labels can range from simple letters and numbers to more complicated symbols. It’s important to pay attention to these labels and match them up with the corresponding colour codes. That way, you’ll be able to determine which wires you need to follow.
