Where is The Parking Brake Wire Located?

Published by Dustin Babich on

For vehicle owners and enthusiasts who engage in DIY audio/video installations or need to perform maintenance involving the parking brake system, understanding the location of the parking brake wire is essential. This wire plays a crucial role in the functionality of in-dash DVD players, navigation systems, and other features that require the vehicle to be parked for operation. In this guide, we’ll explore common locations for the parking brake wire and its importance in vehicle safety and functionality.

Short Answer: The parking brake wire is typically connected to the parking brake mechanism itself, often found under the dashboard near the parking brake pedal in vehicles with a foot-operated brake, or near the center console in vehicles with a hand-operated brake. It’s usually identifiable by its green color in most aftermarket installations but may vary in factory setups.


The parking brake wire serves as a safety feature in vehicles, ensuring certain functions are only accessible when the vehicle is securely parked. For aftermarket installations, such as head units with video displays, this wire needs to be connected to the parking brake system to comply with safety regulations. Knowing its location is vital for proper installation and troubleshooting.

Key Takeaways:

  • The parking brake wire is a safety feature connected to the vehicle’s parking brake system.
  • It is most commonly found under the dashboard or near the center console, depending on the type of parking brake.
  • Identifying and properly connecting this wire is crucial for the functionality of certain in-vehicle systems.

Common Locations for the Parking Brake Wire

In vehicles with a foot-operated parking brake, the parking brake wire is usually located under the dashboard. It’s connected to the parking brake mechanism, which can be found near the driver’s left foot area. Look for a wire that runs along or is connected to the parking brake lever mechanism.

Near the Center Console

For vehicles with a hand-operated parking brake, typically located between the front driver and passenger seats, the parking brake wire can often be found near the base of the handbrake lever, within the center console’s internal structure. Removing parts of the center console may be necessary to access it.

In the Wiring Harness

In some modern vehicles, the parking brake signal is integrated into a more complex wiring system and may be accessible through the main wiring harness behind the dash. In these cases, consulting a vehicle wiring diagram or professional help may be necessary to identify the correct wire.

The Importance of the Parking Brake Wire

The parking brake wire is not just another wire in your vehicle’s complex electrical system; it’s a critical component for ensuring that certain features are used safely. Its connection is essential for the functionality of in-dash units that are designed to operate only when the vehicle is parked, preventing driver distraction.


Whether you’re installing a new head unit, troubleshooting, or simply curious about your vehicle’s electrical system, knowing the location of the parking brake wire is essential. This knowledge ensures the safe and correct use of vehicle features that require the car to be parked, contributing to overall road safety.
