How to Install an Electric Brake Controller on F800 W with Air Brakes

[MikePhua]

Introduction
For vehicles equipped with air brake systems, such as the F800 W model, many owners may want to add an electric brake controller to enhance braking precision and safety. An electric brake controller allows for more accurate control of the trailer's brakes, making towing safer and more comfortable. This article outlines the steps for installing an electric brake controller on the F800 W.
Installation Steps

1. Choosing the Right Electric Brake Controller
   • There are various electric brake controllers available in the market. Popular brands include Tekonsha, Curt, and Draw-Tite. Ensure that the controller you choose is compatible with the F800 W and its air brake system.
     
2. Gathering Tools and Materials
   • To install the electric brake controller, you'll need the following tools:
     • Screwdrivers, wrenches
       
     • Cable cutters
       
     • Power tools (if needed)
       
     • Wire connectors, fuses, and battery terminals
       
     • Mounting brackets for the controller
       
3. Disconnect the Vehicle’s Battery
   • Before performing any electrical work, always ensure safety by disconnecting the vehicle’s battery to prevent short circuits or electrical accidents during the installation process.
     
4. Choose a Mounting Location
   • The brake controller is typically mounted in a position that is easily accessible to the driver, such as under the dashboard. The chosen spot should allow the controller to sit securely while providing the driver easy access during operation.
     
5. Install the Mounting Bracket
   • Once you have selected the proper location, use the mounting bracket to secure the electric brake controller in place. Make sure the bracket is sturdy, and the wiring can be routed easily.
     
6. Connect the Wiring
   • Using wire connectors, connect the brake controller to the vehicle’s electrical system. This generally involves wiring the controller to the brake light circuit and connecting it to the battery's positive terminal and brake light switch.
     
   • Note: For safety and stability, use wires with fuses to avoid overloading the system.
     
7. Connect to the Air Brake System
   • Since the F800 W uses an air brake system, you may need to connect the electric brake controller to the air brake control system. Ensure that the air lines are correctly attached, and check for any leaks or loose connections.
     
8. Test and Adjust
   • After installation, reconnect the battery and start the vehicle to check the functionality of the electric brake controller. Test the trailer brake response to ensure that the controller is adjusting brake force correctly and make adjustments if needed.
     
9. Check the Brake System
   • After the installation, double-check all connections to ensure they are secure. Inspect the air brake system for any leaks or irregularities in pressure, ensuring that the electric brake controller is functioning properly.
     

Common Issues and Solutions

• Delayed Brake Response: If the brake controller responds slowly or unevenly, it could indicate poor electrical connections or improper mounting. Recheck all connections and make sure that the wires are not damaged or loose.
  
• Brake System Malfunction: If the brake system fails, immediately stop using the vehicle and inspect the brake system. Ensure that both the air brake system and the electric brake controller are properly connected.
  

Conclusion
Installing an electric brake controller on an F800 W with an air brake system can greatly improve brake control precision when towing. By selecting the right controller, properly installing it, and fine-tuning its operation, you can enhance both safety and driving comfort, especially when hauling heavy loads.
