Which Brake Controller Harness is Needed for 2017 Ford Motorhome

Question:

I am looking for a plug-in wiring adapter for a brake controller P3. The vehicle is a 2017 ford motorhome. The wiring adapter in your original email you sent said to use the #3035-P. I do not believe this is the correct plug for my particular vehicle. I have included photos to help assist you with your research. My connector has seven pins, which I believe are used for the turn signal to the trailer. If theses two pins are not used how is the signal sent to the trailer? Hopefully, both images were sent. It only wants to load one image. Thanks

Are you sure that is the brake controller port? You actually want the part # 3034-P which is accessed behind the panel on the dash like what you see in the attached picture.
