After market brake controller issue

[Fuzz0614]

I have a 2019 ram 1500 new body style and having one hell of a time with brake controller working. I have power to brake controller but when hit brakes nothing. If I use Manuel slide I get voltage to brake controller but it trips a code saying auto park disabled and traction control system service. I have a brand new tekonsha p2 any suggestions on what to do. I call a ram dealership and they said they never heard of anything like this. Looking for any and all input. Thanks
