Which harness is right for my car?

Add your vehicle to the 'My Garage' feature at the top right hand side of our website to instantly access a selection of wiring harnesses specifically tailored for your car model. By inputting your vehicle details, you will gain precise compatibility, allowing you to confidently select the right wiring harness that meets the exact specifications of your car.

Can I reuse an old head unit's wiring harness?

Each wiring harness is designed specifically for your car's head unit, meaning these are not interchangeable between different models. For the best compatibility and functionality, it's recommended to use a new wiring harness that matches your head unit and vehicle, ensuring a smooth and secure installation process.
