What is a Wiring Diagram?

A wiring diagram is a visual representation of the electrical system of a car. It contains a series of symbols that correspond to every component in the vehicle, showing how each part is connected and how they interact with each other. Wiring diagrams have several uses, such as helping to identify short circuits or showing how the components are hooked up and connected to one another. When reading wiring diagrams, it’s important to follow a few steps to ensure accuracy:

Identify each symbol and its function prior to reading the diagram.

Start from the left and work your way across, from the diagrams power source.

Make sure to follow the direction of the flow of electricity.

Label each component to connect with its corresponding label on the wiring diagram.

Understanding the wiring diagram of your 1979 Toyota Land Cruiser can serve as the foundation for troubleshooting any problems. Here's a breakdown of the main components you'll need to know to get started.

Ignition Switch

The ignition switch powers the electrical system of your vehicle. It's located near the steering wheel and is responsible for allowing the engine to start and allowing the electrical systems to come online.

Headlights

Headlights are an important component for visibility, especially when driving in darker conditions.

Horns

The horn is an important safety device and helps alert drivers and pedestrians of potential dangers. Most Land Cruisers have one or two horns, wired directly to the battery and the fuse box, depending on the model.

Power accessories

In more modern models, power accessories often include features like CD players, climate control systems, power windows, power door locks, fog lights, air conditioning and Bluetooth connectivity. All these components interact with one another and are connected with the wiring diagram's specified wires.
