Volkswagen Beetles have been around for many years, and are still a popular car today. They have undergone many changes over the years, including changes to the fuel injection system. In 1979, the Volkswagen Beetle got a new fuel injection system, which required a wiring diagram for proper installation. This article will cover everything you need to know about the 1979 VW Beetle fuel injection wiring diagram.
What is a Fuel Injection Wiring Diagram?
A fuel injection wiring diagram is a diagram that shows the electrical connections between the different components of a fuel injection system. In the case of the 1979 VW Beetle fuel injection system, the wiring diagram shows the connections between the fuel injectors, the oxygen sensor, the throttle switch, and other components.
Having a wiring diagram is important when installing or troubleshooting a fuel injection system, as it ensures that everything is connected properly and working correctly. Without a wiring diagram, it can be difficult to know which wires go where, which can lead to problems or even damage to the system.
The Components of the 1979 VW Beetle Fuel Injection System
The fuel injection system in the 1979 VW Beetle consisted of several components, including:
| Component | Description |
|---|---|
| Fuel Injectors | Inject fuel into the engine |
| Oxygen Sensor | Measures the oxygen levels in the exhaust and adjusts the fuel injection accordingly |
| Throttle Switch | Monitors the position of the throttle and adjusts the fuel injection |
| Fuel Pump Relay | Controls the fuel pump |
| Fuel Pump | Pumps fuel to the injectors |

Frequently Asked Questions
What is fuel injection?
Fuel injection is a system that delivers fuel to the engine in a precise and controlled manner. It replaced carburetors in many cars in the 1980s and has since become the standard for modern cars.
Why is a wiring diagram important for a fuel injection system?
A wiring diagram is important for a fuel injection system because it shows the connections between all of the components. If the connections are not correct, the system may not work properly or may not work at all.
What is an oxygen sensor?
An oxygen sensor is a sensor that measures the amount of oxygen in the exhaust gases. It sends a signal to the engine computer, which adjusts the fuel injection accordingly.
What is a throttle switch?
A throttle switch is a switch that is activated by the position of the throttle. It sends a signal to the engine computer, which adjusts the fuel injection accordingly.
