Issues Faced When Converting a Car from Right-Hand Drive (RHD) to Left-Hand Drive (LHD)

Introduction

Finding the right car can be a challenging task, especially when it comes to driving standards and regulations. If you've considered purchasing a car that's sold internationally and it is a Right-Hand Drive (RHD) model, converting it to a Left-Hand Drive (LHD) can be an option. However, it's important to understand the considerable challenges and issues you might encounter. In this article, we will explore the specific issues that arise from converting a car from RHD to LHD, detailing the process and potential costs.

Dashboard and Its Impact

The first and arguably the most significant issue is the replacement of the dashboard and other internal components. While a replacement dashboard can be done, especially if you have access to it, there are other options as well. Some cars come with modular dashboards that can be swapped, eliminating the need for a complete replacement, which can be both time-consuming and costly.

Modular Dashboard Solutions

For those who are considering the conversion, it's worth noting that some cars feature modular dashboards, which are designed with easy installation and replacement in mind. These dashboards, often termed 3-piece modular, allow you to swap the ends, thus bypassing the need for a full replacement. This can save a significant amount of money and time in the long run. However, keep in mind that these specific dashboards are not ubiquitous and may not be available for every RHD car.

Steering System and Brake Components

Moving on to the steering system, you will likely have to make substantial adjustments or even replace it. The reasons for this are primarily related to the physical layout and positioning of the components. A steering system designed for RHD might not fit or function properly on an LHD car, requiring a complete replacement or at the very least, modifications. This process requires a good understanding of automotive mechanics and can involve wiring changes to ensure proper functionality.

Brake System Compatibility

The same holds true for the brake system, including the brake booster and brake lines. These components are usually custom-built for the drive type and car models, meaning that RHD cars may have different specifications than LHD cars. Replacing these parts is necessary to ensure the car functions correctly when converted. The process involves removing the existing components, procuring the LHD-compatible replacements, and installing the new parts. Incorrect installation can lead to safety hazards, so it is crucial to be meticulous during this process.

Wiring Harness and Electrical Systems

Wiring Harness

In many cases, the wiring harness needs to be completely replaced. The reason being, the electrical systems in RHD and LHD cars are often designed differently to accommodate their specific drive layouts. A standard wiring harness designed for RHD might not be compatible with an LHD car. Additionally, if the wiring harness is built to be bi-directional, this can save costs, but if it is not, then replacing the entire harness is necessary.

Bi-Directional Wiring Harnesses

Bi-directional wiring harnesses are a step ahead in convenience and cost savings. These harnesses are designed to be used for both RHD and LHD variants of the same car model, making the conversion process smoother and less expensive. However, not all cars and harnesses come with this feature, and you may need to seek out a harness specifically for your model if it’s not already included in your RHD car.

Conclusion and Cost Considerations

Converting a car from Right-Hand Drive (RHD) to Left-Hand Drive (LHD) is a significant undertaking that requires substantial effort and resources. While the process can be done yourself, it involves extensive work, including dashboard replacement, steering and brake system modifications, and wiring harness changes. Professional assistance may be necessary, but can easily exceed the value of the car itself, making the conversion process a costly one. It is essential to weigh the benefits against the potential costs before embarking on such a project.
