By | October 23, 2022



The 1970 El Camino is an iconic classic car that still has a following today. But when it comes to wiring, the El Camino can be a bit of a challenge. To help make sure your El Camino is up and running like it should be, having a wiring diagram on hand can be invaluable.

While the wiring of the El Camino may seem intimidating at first, understanding the basics can help you figure out what needs to be done. This article will provide an overview of the wiring of the 1970 El Camino, including the engine, transmission, ignition, gauges, and other components.

The 1970 El Camino's engine wiring was designed for the General Motors 350 cubic-inch V8, which was a common engine for the El Camino. This included the starter, alternator, distributor, and power steering systems. The wiring harness for the engine was a single wire that connected to the engine bay.

The transmission wiring for the 1970 El Camino is a complex system that includes the transmission control module, shift interlock solenoid, neutral safety switch, reverse light switch, and cruise control switch. These components are all interconnected and must be wired correctly to ensure proper operation of the vehicle.

The ignition system of the 1970 El Camino includes the coil, spark plugs, ballast resistor, and ignition switch. The ignition switch is responsible for sending power to the spark plugs and coil, while the ballast resistor regulates the voltage going to the spark plugs. It's important to get the wiring right here, as any mistake could result in the car not starting.

The gauges in the El Camino are also part of the wiring system. They include the speedometer, tachometer, oil pressure gauge, and fuel gauge. The gauges all connect to the wiring harness in the dash and must be wired properly to ensure accurate readings.

Finally, there are several other components that are connected to the wiring of the El Camino. These include the headlights, turn signals, horn, and other accessories. All of these components must be wired correctly to ensure that they operate properly.

Understanding the wiring of the 1970 El Camino can seem intimidating, but having a wiring diagram can help make it easier. With the right diagram, you can make sure that all of the components are wired correctly and your El Camino is running smoothly.
