1968 Chevy Impala Wiring Diagram

The 1968 Chevy Impala is a classic American car that still holds its place in the automotive world. One of the critical components of this car is the wiring system, which connects all the electrical components, ensuring the car runs smoothly.

In this article, we will discuss the 1968 Chevy Impala wiring diagram, including the components, their functions, and how they are connected to each other.

What is the Wiring Diagram?

The wiring diagram is a schematic representation of the electrical circuitry of a car. It shows how the electrical components, such as the lights, radio, engine components, and other components, are connected and powered.

The wiring diagram for the 1968 Chevy Impala is relevant for both the six-cylinder and V8 engines. The diagram comprises several components that we will discuss below.

Battery and Starter

The battery and starter are the critical components that power the car. The battery provides the electrical energy to start the engine, while the starter motor cranks the engine until it starts running.

The battery is connected to the starter through a thick red wire, which provides a direct path for the electrical energy to flow. The battery also connects to the alternator, which recharges the battery as you drive.

Ignition System

The ignition system includes several components, such as the ignition switch, ignition coil, distributor, and spark plugs. The ignition system transfers electrical energy from the battery to the spark plugs, which then ignite the air-fuel mixture in the engine’s cylinders.

The ignition switch is connected to the battery through a thin red wire and is responsible for turning on or off the electric system. The ignition coil is connected to the battery through a thick pink wire and is responsible for amplifying the electrical energy transmitted to the spark plugs.

Charging System

The charging system consists of the alternator, voltage regulator, and battery. The alternator generates electrical energy while you drive, recharging the battery and providing power to the electrical components.

The voltage regulator is connected to the alternator through a yellow wire and regulates the electrical energy’s output to prevent overcharging the battery.

Lights and Horn

The lights and horn are essential safety components of the car. The headlights, taillights, and turn signals help you see and be seen on the road, while the horn alerts other drivers to your position on the road.

The lights and horn are connected to the battery through a fuse box, which ensures that they receive the correct voltage and protects them from electrical overloading. The lights and horn are also connected to the ignition switch, which controls their operation.
