What is a Wiring Diagram?
A wiring diagram is a visual representation of the electrical components and connections in a vehicle. It shows how the different components are connected and how they interact with each other.

How to Read a Wiring Diagram
Reading a wiring diagram can seem daunting at first, but with a little practice, it can become second nature. The key is to understand the symbols and conventions used in the diagram. Here are some of the most common symbols you’ll encounter:
| Symbol | Description |
|---|---|
| Battery | A large black box with a plus and minus sign |
| Starter Motor | A small black box with a plus and minus sign and two wires coming out of it |
| Ignition Switch | A switch with several wires coming out of it |
| Wire | A line connecting two or more components |
| Connector | A small circle with two or more lines coming out of it |
When you’re looking at a wiring diagram, you’ll see lines connecting various components. These lines represent wires, and the symbols on the lines indicate what type of wire it is (for example, a solid black line might indicate a ground wire).
You’ll also see symbols for connectors, which are where two or more wires come together. These connectors can be either male or female, depending on whether they plug into or receive a plug from another component.
