Location of Brake Controller Connector on 2009 Ford F350

Expert Reply:

The connector for attaching the brake controller is clipped to the back of the storage tray located in the dash, under the climate controls. To access the connector, remove the tray and unclip it from the rear of the tray. If you have the OEM wiring adapter that was included with the vehicle, it would wire to the brake controller as follows. The yellow wire on the harness attaches to the red wire on the controller. The blue wire on the harness attaches to the blue brake controller wire, the black wire on the harness attaches to the white wire on the controller, and the red harness wire connects to the black wire on the controller. If you do not have the OEM Wiring Adapter, we offer a replacement Wiring Adapter, part # 20270.
