To find the vehicle brake control harness connector on your F-150 for your CURT 51436 Brake Control Adapter Harness, follow these steps. First, open the driver's side door and look under the dashboard, positioned above the brake pedal. The connector is typically taped to another harness and should resemble the connector on your CURT brake control harness. Carefully remove any tape or protective covering from the connector, making sure not to damage the locking tabs. Next, plug the CURT brake control harness connector into the vehicle's connector, ensuring it's fully inserted and the locking tabs are engaged. Then, route the brake control harness along the back of the dash, bringing it out the bottom towards the brake control unit. Insert the black connector from the brake control harness into the quick plug connector on the brake control. Secure the harness using the provided cable ties, taking care to avoid any pinch points. Finally, complete the installation by following the specific instructions that came with your brake control unit, including mounting the unit as directed and performing the testing procedures outlined in the brake control's user manual. If you cannot find the harness connector under the dash as described, check the alternative instructions in the installation manual; these often apply to vehicles with a shifter lever in the center console.
