The easiest way is to pick up a harness extension. I bought mine from the dealer I got the brake controler from. Dealer may have also. Watch out if yours is an 03 as they changed the wiring mid year and you may have to switch a couple of wires. The Avalanche forum has more on this.

What is the location of the factory trailer wiring connector for the electric brake control on a 2007 Dodge Ram 1500 with tow package?
The connecting outlet is located under the left side of the dash above the emergency brake. You are looking for a plug in outlet that is color coded blue. The connecting pigtail that you can get from any Dodge dealer will also be blue on the end that you are going to plug in. Connect them together and then you are ready to connect the other end to your electric brake controller.
How do you install electric trailer brakes on a 2007 Dodge Ram truck?
The wiring is already run for you. It's a simple matter of wiring up the brake controller and installing it in the cabin.
