If you’re a hands-on Jeep owner, you can save a significant amount of money by tackling this installation yourself. This guide will walk you through the process of installing a trailer brake controller at home in under two hours, and importantly, how to flash the necessary software using a BAFX Products Bluetooth Diagnostic OBDII Reader and readily available software, ensuring seamless integration with your Jeep’s UConnect system. Forget expensive dealership visits for software updates – let’s get started!
Parts You’ll Need

With all these parts, including the BAFX OBDII reader and software, the total cost should be around $240, a substantial saving compared to dealership prices. Purchasing the BAFX Products Bluetooth Diagnostic OBDII Reader and AlfaOBD software not only enables you to install the trailer brake controller but also equips you with the ability to read and clear engine codes and perform other software updates in the future – a valuable tool for any Jeep owner.
Step-by-Step Installation Guide
Step 1: Disconnect the Negative Battery Terminal
Safety first! Before starting any electrical work on your Jeep, disconnect the negative battery terminal. Locate the negative terminal in your engine bay and use a 10mm wrench or similar tool to loosen and remove the nut. Ensure the negative cable is safely tucked away from the battery terminal to prevent accidental reconnection during the installation process.
Step 2: Remove the Center Stack of the Dash
Removing the center stack might seem daunting, but it’s a straightforward process. Begin by locating and removing the two screws at the top of the center stack. Once the screws are removed, place one hand in the top cupped area and the other at the bottom of the trim piece. Gently but firmly pull straight out towards the back of the cab. The center stack is held in place by clips and will release with a firm pull. It’s a robust piece, so don’t worry about breaking it with reasonable force.
You’ll encounter connectors on the back of the center stack. For easier access and to prevent any wiring damage, it’s recommended to disconnect all the plugs. Most connectors have a small latch that needs to be depressed to release them. If you have larger fingers, a small screwdriver can assist in depressing these latches.
Step 3: Locate and Unwrap the Trailer Brake Connector
Once the center stack is removed, locate the connector that is pre-wired for the trailer brake controller. This connector is usually wrapped in cloth tape. Carefully unwrap the tape to expose the connector. This is the connector you will use to plug in your new trailer brake switch.

Step 5: Software Flashing with BAFX OBDII and AlfaOBD
This is where your BAFX Products Bluetooth Diagnostic OBDII Reader and AlfaOBD software come into play.
- Connect the Security Gateway Bypass: Install the FCA Security Gateway Bypass Module as per its instructions. This module is essential to allow your BAFX OBDII reader to communicate with the Jeep’s computer system for software modifications.
- Connect BAFX OBDII Reader: Plug your BAFX Products Bluetooth Diagnostic OBDII Reader into the OBDII port of your Jeep, typically located under the dashboard on the driver’s side.
- Pair with AlfaOBD: Turn your Jeep’s ignition to the “ON” position (engine off). Launch the AlfaOBD app on your smartphone or Windows device and establish a Bluetooth connection with your BAFX OBDII reader.
- Configure Trailer Brake Controller: Within the AlfaOBD app, navigate to the vehicle configuration or programming section. Locate the settings related to trailer towing and brake controller. Enable the trailer brake controller function and follow the prompts within AlfaOBD to write the configuration changes to your Jeep’s computer. This process will vary slightly depending on the AlfaOBD version and your specific Jeep model, so refer to AlfaOBD documentation or online forums for precise instructions for your vehicle.
- Verify Installation: After flashing the software, use AlfaOBD and your BAFX OBDII reader to check for any error codes and ensure the trailer brake controller is recognized by the UConnect system. You can typically find trailer brake controller settings within the UConnect trailer towing menu after successful software flashing.
