- System Diagrams: These focus on individual electrical systems (e.g., the starter system, the cooling fan system).
- Main Harness Diagrams: These illustrate the routing of the primary wiring harnesses throughout the vehicle.
- Component Diagrams: These show the internal wiring of specific components.
A typical diagram might look something like this simplified representation:
| Component A (e.g., Battery) | Wire | Component B (e.g., Switch) |
|---|---|---|
| + Terminal | ------ | Input Terminal |
