Question:

Thank you for the reply. Im going to check it out now. But i did buy the wire harness that plugs into the box under the dash by the left foot. And connected that to the new brake controller as directed. So I'm not to use that anymore?

Factory Integrated Brake Controllers do not always function as well as they hoped. You will be much happier with the Redarc Tow-Pro Elite # RED44FR which will give you much more adjustability and function settings not available with your factory integrated controller. There are connections under your dash and connections under your hood you will need to address for the new controller function and disconnection of the factory controller. I've attached an article to assist in the complete process which also includes photos. You do not need to do anything further with the factory integrated controller.

You will still use the wiring harness # 3016-S for your wiring inside the cab under the dash. The newer models have the easy wiring harness connection instead of the bundle of wires. The other wiring you need to do under the hood will activate the power wire that harness inside the cab uses. You will follow the attached article for that portion of the installation. Then you simply need to disconnect your factory controller.
