Step-by-Step Guide to Installing Your Trailer Brake Controller

Step 1: Gather Your Parts – Affordable and Accessible

The key to a successful DIY project is having all the necessary parts at hand. For this trailer brake controller installation on a RAM 1500 with a 12″ touchscreen (parts may be compatible with other models, but always verify compatibility for your specific vehicle), you’ll need the following components. We’ve focused on sourcing cost-effective options, keeping in mind the “bulk cheap” aspect when considering tools like the OBD2 scanner.

Parts List:

• Trailer Tow Module: 68277136af – This is the core component for managing your trailer brakes. You can find this at various online retailers or parts suppliers.
• Switch Instrument Panel: 68309259ac (Ensure this is the correct part for your model year and screen size, especially for 12″ screens and potentially others) – This switch integrates into your dashboard for easy brake controller adjustments.
• Module Bracket: 68346572ab – A small but essential bracket for mounting the trailer tow module securely.
• Nuts (x3): 6510468aa – These are the correct nuts for securing the module bracket.
• Screws (x3): 6101946 – Matching screws for the nuts, ensuring a firm and stable installation.
• OBD2 Reader: BAFX Products OBD2 Bluetooth Reader (or equivalent BAFX OBD2 bulk cheap option from Amazon or other online retailers) – Around $25. This is your key to unlocking the software side of the installation. A BAFX OBD2 scanner is a popular and affordable choice for DIYers.
• FCA Security Gateway Bypass Module: Around $50. This module is necessary to bypass the security gateway in modern FCA (Fiat Chrysler Automobiles) vehicles, allowing you to make software changes.
• AlfaOBD Software: Around $50 from your app store (available for Android and Windows). This powerful software, combined with your BAFX OBD2 bulk cheap scanner, allows you to perform the necessary software flashing.

Total Estimated Cost for Parts and Software: ~$237.60

Cost-Saving Tip: While we recommend the AlfaOBD software and a BAFX OBD2 bulk cheap scanner for full control and future diagnostics, you can potentially save around $100 if your local dealership offers software flashing for a lower price. However, investing in the BAFX OBD2 scanner and AlfaOBD provides long-term value, enabling you to read engine codes, clear errors, and perform other software updates beyond just the trailer brake controller. The BAFX OBD2 scanner is a worthwhile investment for any DIY car enthusiast.

Step 2: Disconnect the Negative Battery Terminal – Safety First

Before starting any electrical work on your vehicle, it’s crucial to disconnect the negative battery terminal. This prevents accidental shorts and ensures your safety throughout the installation process.

1. Locate your vehicle’s battery, typically under the hood.
2. Identify the negative terminal, usually marked with a (-) sign.
3. Use a 10mm wrench (or equivalent) to loosen the nut on the negative terminal.
4. Carefully disconnect the negative cable and tuck it aside, ensuring it doesn’t accidentally reconnect with the terminal.

Step 3: Remove the Center Stack of the Dash – Accessing the Installation Point

Gaining access to the area where you’ll install the trailer brake controller module requires removing the center stack of your dash. Don’t worry, it’s designed to be removed without specialized tools.

1. Locate and remove the two screws at the top of the center dash stack. These are usually easily visible.

2. Place one hand in the cupped area at the top of the dash piece and the other at the bottom.

3. Pull firmly and straight out towards the back of the cab. The center stack is held in place by clips and will detach with a bit of force. It’s a robust piece, so gentle but firm pressure is key – no gorilla strength needed!

4. You’ll see connectors on the back of the console. For the connector pictured below, you might need a small screwdriver to gently depress the latch to disconnect it. If you have larger fingers, disconnecting all plugs on the back of the console is recommended. This reduces strain on the wiring and makes handling the console much easier, minimizing the risk of damage.

Step 4: Unwrapping the Trailer Brake Switch Connector – Preparing for Installation

Located within the dash, you’ll find a connector wrapped in cloth tape. This is the designated connector for your new trailer brake switch.

1. Carefully locate the wiring harness within the dash cavity where you removed the center stack.
2. Identify the connector wrapped in cloth tape.
3. Unwrap the tape to expose the connector. This is where you’ll connect the new trailer brake switch in the subsequent steps.

A full article would detail the module installation, switch installation, software flashing using AlfaOBD and the BAFX OBD2 bulk cheap scanner, and final testing).
