I have a 2021 Ram 1500 laramie, 5.7 non- etorque. I'm installing the integrated trailer brake controller and want to use AlphaOBD to activate it. I used it on a 2019 that I had with success. Have the procesdures changed any from 2019 to 2021? Will the Alpha program that I bought in 2019 still work with the 2021? Thanks for your help.
