1979 Ford F150 Starter Solenoid Wiring Diagram

If you own a 1979 Ford F150 and are experiencing issues with the starter solenoid wiring, you’re not alone. This is a common problem that many Ford F150 owners face, and it can be frustrating to deal with if you’re not experienced in automotive wiring. In this article, we’ll take a closer look at the 1979 Ford F150 starter solenoid wiring diagram and provide you with some helpful tips to get your truck back on the road.

What Is a Starter Solenoid?

Before we dive into the wiring diagram, it’s important to understand what a starter solenoid is and what it does. The starter solenoid is an electrical switch that controls the flow of electricity from the battery to the starter motor. It acts as a relay between the battery and the starter motor, allowing the motor to turn over and start the engine. Without a properly functioning starter solenoid, your engine won’t start.

What Are Some Common Signs of a Bad Starter Solenoid?

If you’re experiencing issues with your starter solenoid, here are some common signs to look out for:

Issue Description
Clicking Sound You may hear a clicking sound when you turn the key in the ignition, but the engine won’t start.
No Sound When you turn the key, there’s no sound at all – not even a clicking sound. This could indicate that there’s no power getting to the starter motor.
Starter Motor Runs But Doesn’t Start the Engine If you can hear the starter motor running, but the engine won’t start, this could be due to a faulty starter solenoid.

Understanding the 1979 Ford F150 Starter Solenoid Wiring Diagram

The 1979 Ford F150 starter solenoid wiring diagram consists of several components. We’ll break down each component and explain how they work together to start your engine.

Battery

The battery is the primary source of power for your Ford F150. It provides the necessary voltage to start your engine and power your vehicle’s electrical system.

Starter Motor

The starter motor is responsible for turning over the engine when you turn the key in the ignition. It’s an electric motor that’s powered by the battery.

Starter Solenoid

The starter solenoid acts as a switch between the battery and the starter motor. When you turn the key in the ignition, the solenoid sends an electrical signal to the starter motor, which then turns over the engine.

Ignition Switch

The ignition switch is located on the steering column and is responsible for sending an electrical signal to the solenoid when you turn the key in the ignition. This signal activates the solenoid, which sends power to the starter motor.

Wiring

The wiring in your Ford F150 is responsible for connecting all of the electrical components together. Without proper wiring, your vehicle won’t start or function properly.

How to Wire a 1979 Ford F150 Starter Solenoid

If you’re experiencing issues with your starter solenoid wiring, you may need to rewire it. Here’s a step-by-step guide on how to wire a 1979 Ford F150 starter solenoid:

Step 1: Disconnect the Battery

Before you begin any electrical work on your vehicle, it’s important to disconnect the battery. This will prevent any accidental electrical shocks or short circuits.

Step 2: Locate the Starter Solenoid

The starter solenoid is located on the passenger side fender well. It’s a small cylindrical component with several wires connected to it.

Step 3: Remove the Old Wiring

If you’re rewiring the starter solenoid, you’ll need to remove the old wiring. Use a wire stripper to remove any damaged or corroded wires.

Step 4: Connect the New Wiring

Once you’ve removed the old wiring, it’s time to connect the new wiring. Follow the wiring diagram carefully to ensure that you’re connecting each wire to the correct terminal.

Step 5: Reconnect the Battery

Once you’ve connected the new wiring, it’s time to reconnect the battery. Double-check all of your connections to ensure that they’re secure and free of any damage or corrosion.
