Why Do DIYers Need Wiring Diagrams?

Tips for Understanding Wiring Diagrams

Although wiring diagrams are fairly simple documents, they can look intimidating at first. To make understanding them easier, try color coding the wires based on what they power (for example, the positive wire for the headlights should be colored red). Then, label each component of the diagram with the corresponding part name. That way, you'll be able to quickly recognize which part the diagram is describing without having to figure it out yourself.

Finally, take your time studying the diagram. Don't rush through it because you're anxious to get started working on the car. Try to look over the diagram as many times as necessary until you understand how the circuit works and where each part is connected. This will save you a lot of time and frustration in the long run.
