2005 Dodge Dakota Owner Manual - Page 261

STARTING AND OPERATING 261 If you regularly pull a trailer, regardless of the trailer size, stop and turn signals on the trailer are recommended for motoring safety. When the additional trailer lighting is connected to the vehicle, the flasher does not provide an indication of outside lamp/bulb failure. Therefore, an occasional visual check around the vehicle is recommended. Once the trailer is removed the above indication will return to the vehicle. All Dakota models require an electrically actuated electric brake controller. A blue colored connector for electric brake hookup is located under the instrument panel above the brake pedal. Heavy trailer towing also may require breakaway electric trailer brakes, anti-sway devices or equalizing hitches for safe operation. Such devices are commonly required by state law. Trailer Tow Wiring The Trailer Tow Package includes a 4 and 7 pin wiring harness located at the rear underbody of the vehicle. NOTE: Connect trailer lighting and brakes using factory harnesses only. Do not cut or splice wiring to the brake circuits. 5 WARNING! The direct connection of hydraulic brake lines from vehicle brake system to trailer system is not acceptable. The extra load may cause brake failure and you may be injured.
