I have a question regarding the pro trailer back up assist. I just purchased a 2021 F150 XLT 3.5 hybrid. I have the max tow package, 360 cameras and I believe every option necessary to utilize the pro trailer back up assist. My question is, from research that I have done it is necessary to install a sensor on the trailer which includes and additional wire harness to be plugged into the receptacle below the seven pin trailer connector in order for the pro back up assist to work. I haven't been able to get satisfactory answers from anyone at Ford. Any information you can provide would be greatly appreciated. Thank you
