Dakota 2WD V8-4.7L VIN J (2005)
Trailer Lamps: Description and Operation
WIRING-TRAILER TOW
Vehicles equipped with a factory-installed trailer tow package include an electric trailer brake wiring provision that terminates at a connector located on
top of the large body harness connection under the instrument panel to the left of the brake pedal, as well as an electric trailer brake pigtail harness and
an instruction card (2) that are stored in the glove box (1) when the vehicle is shipped from the factory.
If an aftermarket electric brake controller is used, the electric brake pigtail harness supplied will make installation easier. The connection (blue 4-way
connector) for the harness is located under the instrument panel to the left of the brake pedal on top of the large body harness connection.
The battery line of this harness may be used to charge the trailer battery. However, a battery isolation unit is not supplied and the trailer battery may
discharge the truck battery when the engine is not running. The battery line is protected by a fuse or a circuit breaker. Refer to the owner's manual in the
vehicle glove box for type, location, and ampere rating.
