Disclaimer: This process involves modifying the vehicle's wiring, which should be done with caution. It is recommended that you consult with a professional automotive technician or installer to ensure proper installation and to avoid any potential risks or damage to your vehicle.
1. Locate the ignition switch: Depending on your vehicle model, the ignition switch may be located in different positions. It is commonly found on the steering column or dashboard. Identify the ignition switch where you insert the key or turn it to start the vehicle.
2. Identify the wire colors: You will need to identify three specific wires:
- Starter Motor Wire: This wire provides power to the starter motor and cranks the engine when you turn the key or press the remote start button. The color of this wire can vary, but it is often red or yellow with a red stripe.
- Primary Ignition Wire: This wire provides power to the ignition system and allows the engine to run once it is started. This wire is typically red, orange, or yellow.
- Ground Wire: This wire provides a grounding path for the electrical circuit. The ground wire is usually black.
3. Disconnect the battery: Before working on any electrical components, it is important to disconnect the battery to avoid any electrical shocks or damage to the vehicle's electrical system.
4. Access the ignition switch wiring: Once the battery is disconnected, you will need to gain access to the ignition switch wiring. This may involve removing the steering column covers or plastic panels around the dashboard.
5. Use a multimeter to identify wires: Use a multimeter to test the wires and confirm their functions. You can do this by setting the multimeter to the "Voltage" setting and testing the wires while turning the key or attempting to remote start the vehicle. The starter motor wire will show a voltage reading when the ignition is turned to the "Start" position or when the remote start button is pressed. The primary ignition wire will also show a voltage reading when the ignition is turned on, but not in the "Start" position.
6. Cut the wires: Once you have identified the correct wires, you can cut them. Make sure to leave enough wire length so that you can reconnect them later or install a bypass module.
7. Install the remote start module: Once the wires are cut, you can install the remote start module according to the manufacturer's instructions. The module will typically have terminals or connectors that you can attach to the cut wires.
8. Reconnect the battery: After the remote start module is installed, reconnect the battery.
9. Test the remote start system: Try remote starting the vehicle using the remote transmitter or the smartphone app (if applicable) provided by the remote start kit. Make sure the system functions correctly.
Remember, this process may vary depending on the specific vehicle model and type of remote start kit being installed. It is essential to follow the instructions that come with your remote start kit and to verify the wire colors and functions with a multimeter to ensure proper installation. If you are not comfortable performing this task or do not have the necessary tools or knowledge, it is best to seek assistance from a qualified professional.
