How to Wire a Push Start Button

A push start button is a popular feature in modern cars. It allows you to start the engine by pressing a button and eliminates the need for a traditional key to start the car. Wiring a push start button is an easy way to modernize your car’s ignition system. You will need a few tools and custom wires and cables to get started, but you will surely benefit from the simplicity provided by your push start. Below, you will find instructions on how to wire a push start button.

How to Wire a Push Start Button

Customizing your car with a push start button requires careful attention and ultra-flexible wire. These are necessary to ensure your safety as you deal with the car’s electrical connections. Consider the following steps if you are wiring a push start button in your car.

Gather Your Tools

You will need several tools and materials to get started with the installation process. Specifically, you will need to acquire a push start button, wire cutters and strippers, electrical tape, multimeter, screwdrivers, and heat shrink tubing. You will also need custom wires, cables, and a wiring diagram for your car. These are the basic tools and materials necessary to complete the push-start button process.

Research Your Car’s Ignition System

Before you start tinkering with anything, go over your car’s wiring diagram. You must do this to ensure you have a complete understanding of how the ignition system operates. It also allows you to safely and accurately make modifications to the system. Locate the power source, starter wire, accessory wire, and ground wire. These are necessary to understand how to connect the power source to the motor.

Disconnect The Battery and Locate Wires

As you navigate the process, begin by turning off the ignition. From there, disconnect the negative terminal of the car battery. This step is crucial to preventing short circuits or electrical shock. Working on the wiring of your car requires care and caution for your safety.

Use the wiring diagram from your car to locate the ignition wires. Test the wires with a multimeter tool to ensure they are fully functioning. Ensuring the wires are fully functioning prevents mistakes. If you are not careful, these mistakes can cause serious damage to your car’s electrical system.

Prepare The Push Start Button

Find and assess the push start button connection points, namely the power, ground, accessory, and starter points. You can use ultra-flexible wire for connections in places where flexibility is necessary. Using the right type of wire ensures a durable and long-lasting connection. 

Connect and Test the Wires

Connect the power, starter, accessory, and ground wires. You should connect a custom wire to the power source and to the push start button’s power terminal. Use a fuse inline for safety purposes. Specifically, it will reduce the risk of electrical surges or other damage. Attach the starter wire from the ignition system to the starter terminal on the push button. 

Next, connect the accessory wire to the designated terminal on the push button. This will power the secondary systems, including the dashboard and radio. Lastly, connect the ground wire to the ground terminal. Connect the car battery and test the connections to see if everything is working properly. 

Mount the Push Start Button

Once you have secured and tested the wires, mount the push start button. Choose a location on your dashboard that is convenient. Placing it somewhere that is easily accessible is important. Use a drill to create a hole to secure the button with the push start button’s mounting hardware.
