My Experience with RV and Ambulance Conversion: Wiring Driving Lights and Making Modifications

As someone who has embarked on an RV and ambulance conversion journey, I can tell you that it’s an exciting and rewarding process. I’ve had to tackle various tasks, such as wiring driving lights and making modifications to my plans. In this article, I’ll share my experience hooking up driving lights, modifying plans, and running wire in my ambulance and RV conversion project.

  1. Reconnecting Driving Lights in My Ambulance Conversion

One thing I had to deal with during my conversion was reconnecting the driving lights to ensure proper visibility and safety on the road. Here’s how I managed to hook up the driving lights in my ambulance conversion:

A. First, I found the wiring harness for the driving lights and identified the power and ground wires. In my case, the power wire was red, and the ground wire was black. I checked my vehicle’s wiring diagram to confirm the wire colors. B. Next, I connected the power wire to the corresponding terminal on the driving light and secured it with a suitable connector. C. I then attached the ground wire to my vehicle’s chassis, ensuring a secure connection. D. Finally, I tested the driving lights to make sure they were functioning correctly.

  1. Modifying Plans and Removing Paneling in My Ambulance Conversion

During my conversion, I realized I needed to make some changes to my original plans, like removing or adjusting paneling. Here’s how I went about this process:

A. I assessed the existing layout and pinpointed areas that needed modification. B. I carefully removed the paneling, taking care not to damage any surrounding structures or wiring. C. I reconfigured the layout based on my revised plans, focusing on optimal space utilization and functionality. D. I reinstalled or replaced the paneling as necessary, securing it with the appropriate fasteners and adhesive.

  1. Removing Light Bars in My Ambulance Conversion

Since light bars on an ambulance aren’t necessary for RV use, I decided to remove them. This task proved to be somewhat challenging, but with patience and the right tools, I successfully removed both light bars.

  1. Running Wire for Electrical Modifications in My Ambulance Conversion

As I made modifications to my ambulance conversion, I needed to run additional wiring for new electrical components and reconfigure existing systems. When running wire, I followed these tips:

A. I planned my wiring routes carefully to minimize the risk of damage or tangling. B. I used the correct gauge and type of wire for each component, as specified in my vehicle’s wiring diagram and the component’s documentation. C. I secured the wiring using cable ties, clips, or conduit to protect it from damage and maintain a neat appearance. D. I tested all new electrical connections and components to ensure proper functioning and safety.

Ambulance Conversion


In my ambulance and RV conversion journey, hooking up driving lights, making modifications to plans, and running wire were essential steps. By taking the time to carefully plan and execute these tasks, I created a safe, functional, and comfortable mobile living space. If you’re ever unsure about any aspect of the wiring process, I recommend consulting your vehicle’s owner’s manual, wiring diagram, or a professional mechanic.

A Quick Guide to Brake Lights Wiring

Brake lights are an essential safety feature on every vehicle, alerting other drivers when you’re slowing down or stopping. Proper brake lights wiring is crucial to ensure their correct functioning. This article will provide a brief guide on brake lights wiring, helping you to understand the process and maintain your vehicle’s safety features.

  1. Understanding the Brake Light Circuit

The brake light circuit comprises a power source (the battery), a brake light switch, wiring, and the brake light bulbs. When you press the brake pedal, the brake light switch gets activated, closing the circuit and allowing the current to flow through the wiring and illuminate the brake lights.

  1. Locating the Brake Light Switch

The brake light switch is typically located near the top of the brake pedal arm. To access it, you may need to remove a panel or cover under the dashboard. The switch will have two or more wires connected to it, which may vary in color depending on your vehicle’s make and model.

  1. Identifying the Brake Light Wiring

The brake light wiring usually comprises two wires: a power wire and a ground wire. The power wire carries the current from the battery to the brake lights when the switch is activated. The ground wire, on the other hand, provides a return path for the current, completing the circuit.

In most vehicles, the power wire is colored red or green, while the ground wire is black or brown. However, it’s always best to consult your vehicle’s wiring diagram or owner’s manual to confirm the specific wire colors.

  1. Troubleshooting Brake Light Wiring Issues

If your brake lights aren’t working, there could be a problem with the wiring. Here are some steps to troubleshoot brake light wiring issues:

A. Inspect the brake light switch for any signs of damage, corrosion, or loose connections. If needed, replace the switch. B. Use a multimeter to test the power and ground wires for continuity. If there’s no continuity, the wires may be damaged and need replacement. C. Check the brake light bulbs and replace them if they’re burnt out or damaged. D. Examine the wiring connections at the brake light housing and ensure they’re secure and free of corrosion.

  1. Tips for Proper Brake Light Wiring

To ensure the correct functioning of your brake lights, follow these tips:

A. Use the correct gauge and type of wire for your brake light circuit, as specified in your vehicle’s wiring diagram. B. Secure the wiring using cable ties or clips to prevent it from getting damaged or tangled. C. Regularly inspect your brake light wiring for signs of wear, damage, or corrosion, and address any issues promptly. D. Consider consulting a professional mechanic or electrician if you’re unsure about any aspect of brake light wiring.


Proper brake lights wiring is essential for ensuring your vehicle’s safety on the road. By understanding the brake light circuit, identifying the wiring, and troubleshooting any issues, you can keep your brake lights functioning correctly and maintain your vehicle’s safety features. Always consult your vehicle’s owner’s manual or a professional mechanic if you’re unsure about any aspect of brake light wiring.
