Need help, ITBM 2013 Ram

[TrentonM]

Hello, I just installed an integrated brake controller in my ‘13 ram Laramie. However, when I adjust the gain nothing happens and there is no output, I programmed it into AlfaOBD, but there is a U1057 code. Which states can not communicate with brake controller. I am not sure what to do and need help.

Did you install the computer box under the dash by the right drivers knee area? And are all the connections seated good?
