Question:

Will I need anything more than the alfaobd when flashing a 2022 ram 1500 break controller?

If you're simply wanting to install an aftermarket brake controller on a 2022 Ram 1500 that isn't equipped with the OEM brake controller, you will NOT need to re-flash the ECU.

If that's what you're trying to do, the # 3024-P harness you'd looked at would allow you to install a Tekonsha or Draw-Tite brake controller like the # TK90160 Primus brake controller. Simply plug the # 3024-P harness into the connector under the dash, plug the controller into the harness and you'll be good to go.

If your vehicle has the OEM brake controller, and you'd like to install an aftermarket unit like the Tekonsha Primus I mentioned above, you'll need to unplug the OEM controller and use the # 3024-P harness to plug the controller into the connector that the OEM controller used.

I'm not familiar with the FCA AlfaOBD software, but from what I read on their website, the software allows the:

"adjustment of the car configuration with the ability to activate the newly installed equipment in the Body computer configuration, the Proxy alignment."

You'd want to check with AlfaOBD to see if it will re-flash the computer to install an aftermarket brake controller, or if you'll need to have the dealer handle that for you.
