I have a 2022 expedition timerline, it is not equipped with the heavy tow package. However, I have been looking for the components for the intergraded trailer brake. I have came up with a few parts. As you can see the pig tail is different. I did get a part number off a Expedition Timberline that has one factory installed. The plug that both pig tails plug into, appears to be the same. At this point finding the pig tail is the issue. I am actively looking, I am close. I am not sure ”yet“ if the complete pro towing backing is fully needed. More to follow
