Yes, the CURT 51522 brake control harness is compatible with Audi SQ5, Q5, and Q7 models. All three vehicles have the brake control connector in the same location: underneath the driver-side dash, left of the steering column, near the emergency brake pedal.
The CURT 51522 is a brake control harness that connects to your vehicle's factory brake control system. It allows you to integrate a separate brake control unit with your Audi's existing brake control connector. The harness must be used with a compatible brake control unit, which is installed and tested according to that unit's separate instruction manual.
You will need: a ratchet, 8mm socket, socket extension, panel trim removal tool, and a cutting tool. These tools are required to remove the dash trim panels and access the brake control connector.
The vehicle brake control connector is located underneath the driver-side dash, left of the steering column, near the emergency brake pedal. You will access it by removing the side trim panel from the dash and the lower dash panel.
Follow these steps in order: (1) Remove the driver-side dash side trim panel. (2) Remove the two bolts securing the lower dash panel from underneath. (3) Remove the two small trim panels on each side of the steering column. (4) Remove the bolts under those small panels. (5) Remove the lower dash panel. (6) Locate the vehicle brake control connector. (7) Remove any foam padding from the connector. (8) Insert the CURT harness connector into the vehicle connector, ensuring it is fully seated with locking tabs in place. (9) Insert the black connector into the brake control quick plug connector. (10) Secure the harness with provided cable ties, avoiding pinch points. (11) Reinstall all trim panels and complete the installation per the brake control unit manual.
First, open the driver-side door and remove the side trim panel from the dash to access one bolt. Then, underneath the dash, locate and remove two more bolts. Next, remove the two small trim panels on each side of the steering column and remove the bolts underneath them. Finally, use a trim panel removal tool to carefully remove the lower dash panel, which will expose the vehicle brake control connector.
Remove any foam padding on the vehicle brake control connector before inserting the CURT harness connector. This ensures a proper connection.
The connector is fully inserted when the locking tabs are in place. Make sure the connector is pushed in completely until you feel the locking tabs engage.
The black connector on the CURT brake control harness plugs into the brake control quick plug connector. This connection allows the harness to communicate with the separate brake control unit.
Secure the brake control harness using the provided cable ties. When routing and securing the harness, avoid any pinch points that could damage the wiring.
After completing the harness installation and reinstalling all trim panels, test the system by following the test procedures in the brake control unit's instruction manual. The brake control unit must be mounted as directed in its manual, and then tested according to those procedures. The harness itself does not have separate test steps.
Yes. Avoid pinch points when securing the harness with cable ties, as this could damage the wiring. Additionally, all installation steps must be followed to ensure the brake control harness functions properly. If you are not comfortable performing this installation, contact CURT at 877.287.8634 for assistance.
