You have a problem with your headlights not turning on.
The wiring diagram shows you the specific wire that feeds power to the headlight switch.
It then shows you the connection from the switch to the headlight relay and then to the bulbs.
This allows you to systematically check each point in the circuit for breaks, shorts, or bad connections.
These diagrams are typically presented in a clear, organized format. While the complexity can vary, a good diagram will utilize different colored lines to represent different circuits or functions. This color-coding is incredibly helpful in distinguishing between, for example, the ignition circuit and the lighting circuit.
