So, you’re looking to install a trailer brake controller on your truck and got hit with a hefty dealership quote? Many find themselves in the same boat, facing costs around $700 for a factory trailer brake controller purchase and installation. The good news is, tackling this project yourself is not only possible but also significantly cheaper, especially when you leverage the power of a Bluetooth Obd2 Controller.
This guide will walk you through a DIY installation of a trailer brake controller, highlighting how a bluetooth OBD2 controller is key to completing the job without needing expensive dealership software flashes. You’ll be surprised how quickly and easily you can get this done at home, saving hundreds of dollars and gaining valuable insight into your vehicle’s system.
Parts You’ll Need for Your DIY Install
Before diving in, gather all the necessary parts. This list is tailored for RAM 1500 models, particularly those with the 12-inch touchscreen, but should be generally applicable. Always verify compatibility with your specific vehicle model.
- Trailer Tow Module (Part # 68277136af)
- Switch Instrument Panel (Part # 68309259ac – check for compatibility with your screen size)
- Module Bracket (Part # 68346572ab)
- Nuts x3 (Part # 6510468aa)
- Screws x3 (Part # 6101946)
- Bluetooth OBD2 Controller (like BAFX Products OBD2 Bluetooth Reader)
- FCA Security Gateway Bypass Module
- AlfaOBD Software (available on app stores)
Total estimated cost for parts and software: ~$240. Noticeably less than that $700 dealership quote! The bluetooth OBD2 controller and AlfaOBD software are crucial here, allowing you to perform the necessary software configurations yourself. While you could skip this step and have the dealer flash the software, investing in these tools gives you ongoing access to vehicle diagnostics and customization options beyond just this installation.
Step-by-Step Installation Guide
Let’s get wrenching! Remember to always prioritize safety and double-check connections.
Step 1: Disconnect the Battery
Safety first! Disconnect the negative battery terminal using a 10mm wrench. This prevents any electrical mishaps during the installation process.
Step 2: Remove the Center Dash Stack
This step might seem daunting, but it’s straightforward. Locate and remove the two screws at the top of the center dash stack. Then, using firm but gentle pressure, pull the stack straight out towards the back of the cab. It’s held in place by clips, and it’s designed to be removed.
You’ll encounter connectors on the back of the console. For easier access and to prevent damage, disconnect all of them. A small screwdriver can help depress the latches if needed.
Step 3: Locate the Trailer Brake Connector
Unwrap the cloth tape to reveal the connector you’ll need for the trailer brake switch. This connector is pre-wired and waiting for your new parts!

Unleashing the Power of Your Bluetooth OBD2 Controller
Once the physical installation is complete, the magic happens with your bluetooth OBD2 controller and AlfaOBD software. This is where you activate the trailer brake controller functionality within your truck’s computer system.
Using the FCA Security Gateway Bypass Module, connect your bluetooth OBD2 controller to your vehicle’s OBD2 port. Pair it with your smartphone or tablet, open the AlfaOBD app, and follow the app’s instructions to connect to your vehicle.
Within AlfaOBD, you’ll navigate to the section that allows you to add or modify vehicle features. Specifically, you’ll be enabling the trailer brake controller. This process essentially “flashes” the vehicle’s computer, telling it that a trailer brake controller is now installed and should be active within the UConnect system.
Without a bluetooth OBD2 controller and software like AlfaOBD, this software update would require a trip to the dealership and additional costs. This DIY approach not only saves you money on the installation itself but also equips you with valuable tools for future vehicle diagnostics and modifications.
Benefits of DIY with a Bluetooth OBD2 Controller
Choosing to install your trailer brake controller yourself using a bluetooth OBD2 controller offers several advantages:
- Significant Cost Savings: Avoid hefty dealership labor charges and software flashing fees.
- Empowerment and Control: Gain a deeper understanding of your vehicle’s systems and take control of modifications.
- Versatility Beyond Installation: Your bluetooth OBD2 controller becomes a valuable tool for reading engine codes, clearing errors, and potentially unlocking other software customizations in the future.
- Convenience: Complete the installation in your own time, at your own pace, without dealership appointments.
In conclusion, installing a trailer brake controller is a very achievable DIY project. By utilizing a bluetooth OBD2 controller and readily available software, you can bypass expensive dealership installations, save money, and gain valuable skills and tools. Upgrade your truck and hit the road with confidence, knowing you tackled this upgrade yourself!
