I did a search and did not find exactly what I was looking for. I did see some information about a brake controller but my question is what additional wiring\equipment needs to be purchased to get the brakes on the trailer to work. I have the trailer hitch installed with the new wiring harness you have to buy for the 05's. Do I now ONLY need the brake controller and it will integrate into the new system or do I need more stuff to make it work? I am plannig to tow a car across the country, over mountains and feel I'll really need the trailer brakes.
