Parts You’ll Need for Your DIY Trailer Brake Controller Installation
Before you begin, gather all the necessary parts. This list is tailored for RAM 1500 models, particularly those with the 12-inch touchscreen, but should be compatible with other configurations as well. It’s always wise to double-check compatibility with your specific model year and trim.
Here’s a comprehensive parts list to get you started:
- Trailer Tow Module (68277136af): This is the core component that enables the trailer brake controller functionality.
- Instrument Panel Switch (68309259ac): Specifically designed for models with the 12″ screen, this switch integrates seamlessly into your dashboard. Verify compatibility for other screen sizes.
- Module Bracket (68346572ab): Ensures secure mounting of the trailer tow module.
- Nuts (6510468aa x3): Used for securing the module bracket.
- Screws (6101946 x3): Additional fasteners for the module bracket.
- OBD2 Reader (BAFX Products OBD2 Bluetooth Reader or equivalent): Essential for communicating with your vehicle’s computer system. A Bluetooth reader pairs conveniently with your smartphone or tablet.
- FCA Security Gateway Bypass Module: This module bypasses the security gateway, allowing you to make software changes.
- AlfaOBD Software (App Store): User-friendly software that allows you to configure vehicle settings, including enabling the trailer brake controller.
Total Estimated Cost: ~$237.60 (including software and hardware)
Purchasing these parts yourself can lead to significant savings compared to dealership installation costs. While you can skip the software flashing and have the dealer do it, investing in the OBD2 reader and AlfaOBD software provides long-term benefits. You’ll gain the ability to read and clear engine codes, perform other software updates, and further customize your vehicle.
Step-by-Step Installation Guide for Your OBD2 Trailer Brake Controller
Now that you have all the parts, let’s dive into the installation process. Follow these steps carefully for a successful DIY trailer brake controller installation.
Step 1: Disconnect the Negative Battery Terminal
Safety first! Before working on any electrical components, disconnect the negative battery terminal. Locate the negative terminal on your battery (usually marked with a “-” sign and a black cable). Use a 10mm wrench or equivalent to loosen the nut and carefully disconnect the cable. This prevents electrical shorts and ensures a safe working environment.
Step 2: Remove the Center Stack of the Dash
Removing the center stack might seem daunting, but it’s a straightforward process. Start by removing the two screws located at the top of the center stack trim piece. Once the screws are removed, place one hand in the cupped area at the top of the trim and the other at the bottom. Gently but firmly pull straight out towards the back of the cab. The trim piece is held in place by clips and will pop out with moderate force. Be firm but avoid excessive force to prevent damage.
Step 3: Disconnect Center Stack Connectors
After removing the center stack trim, you’ll see several connectors on the back. For easier access and to prevent any accidental damage, it’s recommended to disconnect all the plugs on the back of the console. These connectors are typically secured with latches. Use a small screwdriver to gently depress the latch on each connector and pull to disconnect. While some connectors might be removable without tools, using a small screwdriver can be helpful, especially in tight spaces. Disconnecting all connectors provides more working room and minimizes the risk of damaging the wiring or console.
Step 4: Locate and Unwrap the Trailer Brake Controller Connector
The connector you need for the trailer brake controller is tucked away and wrapped in cloth tape. Locate this taped connector within the dashboard wiring harness. Carefully unwrap the cloth tape to expose the connector. This is the connector where you will plug in your new trailer brake switch.

To make this a truly comprehensive guide, ideally, we’d continue with the physical installation of the module and switch, and then the software flashing process using AlfaOBD. However, based on the provided source text, this is where the instructions currently end. To further enhance this article, steps on module mounting, switch installation and AlfaOBD programming would be necessary and could be researched and added.)
