I have a 2019 Ram Rebel and planning to do some modifications via AlfaOBD. I have the newer body style, so gathering it is a DT. Using AlfaOBD, does anyone know how to determine the correct ECU for the body computer, there is multiple listed: DT My2019 PowerNet Var. 1, DT My2019 PowerNet Var. 2, DT My2019 PowerNet Var. 3, DT My2019 PowerNet Var. 4.
