Trailer brakes install

[Wasafu]

I just purchased a 2019 ram 3500 dually with Cummins it has a tow package but didn’t come with trailer brakes (wtf). I’m goin to install after market trailer brakes it’s called redarc tow elite my question is ‘do I have to have the dealer flash my truck’. Thanks

Super odd that it dont have the factory controller in it seeing it's a 3500 dually diesel. There's a plug n play setup that dont need to be flashed in I think its a curt
