The harness must be used with a brake control unit (sold separately) and installed according to the manufacturer's instructions.

The brake control harness connector (BH5) is located under the dash, behind the center access panel on the passenger side. The harness routes along the back of the dash and out the bottom to connect to the brake control unit.
1. Make sure the vehicle is off and keys are removed from the ignition. 2. Locate the access panel in the center of the dash on the passenger side. 3. Using a trim panel removal tool, locate the notch in the panel and pry it out and away from the dash. 4. Take care not to damage the trim or locking tabs on the back. 5. Separate the housings attaching the panel and set the panel aside.
If your vehicle has a factory brake control, locate the grey vehicle brake control harness connector plugged into the back of the factory brake control unit. You may need to unplug additional harnesses to access it. Then proceed to Step 4 to connect the CURT harness. Note: Disconnecting the factory brake control will cause a fault code to display on the message center of the dash.
On vehicles without a factory brake control, the grey vehicle brake control harness connector is located on the back of the trim panel directly to the left of the access panel.
