Sounds like you are referencing the below information on installing a brake controller on a 2004 Dodge Ram.
"Your 2004 Dodge should have the connector if the 4-pole connector was factory installed, but it might be a bit tricky to locate.
Behind the emergency brake pedal on the firewall is a white junction box. The blue connector you are looking for is located above the junction box, and is sometimes actually pinned to the top of the box. You might need to give the connector a tug to get it free. The connector is sometimes hidden by the wires entering the top of the box, so sometimes you will need to hunt for it.
If you view the video I have linked to, you can see the connector location at about the :15 second mark. The connector will be blue in color, and will be rectangular in shape.
On models that had the 4-pole, the brake controller voltage output circuit will NOT be ran all the way to the rear of the vehicle, but will terminate under the hood behind the drivers side wheel well (see photo). The blue wire on the side of the connector closest to the front of the vehicle can be tapped into, and a length of 10 gauge wire ran back to the trailer connector. If you need a 12-volt accessory lead, you will need to run another length of 10 gauge wire from the connector to the positive battery terminal, via a 40 amp circuit breaker, part # 9510. If you do not feel like playing wire detective under the hood, you can sever the blue wire a few inches behind the controller and tap in there, as shown in the diagram I produced for you."
The blue wire mentioned is for the output circuit of the brake controller. To power the controller you need to run the black wire to the positive post of the battery. This circuit is totally different from the blue wire and would not get ran to the same place.
Check out the two help links I attached and they will show more details on the process as well.
