What an automotive wiring diagram is.
An automotive wiring diagram shows how a vehicle circuit connects from the battery through protection and switching to a load. Labels identify the voltage, fuse, switch, ground and components a technician needs to trace.
It is a schematic, not a physical harness layout. Use it to understand the circuit logic before you map wire routing and connector locations.

Common questions
What is an automotive wiring diagram?
It is a schematic that shows the electrical components and connections in a vehicle circuit.
What should an automotive wiring diagram include?
Include the system voltage, battery or supply, fuse, switches, relays, loads, ground and any connectors or sensors that matter.
Does it support 12 V and 24 V systems?
State the supply voltage in the description so it appears on the drawing.
Is a wiring diagram the same as a schematic?
A schematic shows electrical connections and function. A physical wiring diagram also shows harness routing, connector locations and wire paths.
