Alpha OBD Bypass Cable

[04RAM_3]

I just bought a 2025 RAM 1500. I don't like the DRL's just being my headlights turning on, and would like to change it so my fog lights come on instead. I did this with my 2019 RAM using Alpha OBD and really liked the outcome.

My question is, do I still need a bypass cable? Will the one from my 2019 work? Or do I need to buy a new cable?

The 2025 Ram trucks changed to the Atlantis High architecture for the electrical system. Everything has pretty much changed, the security gateway isn't in the same spot and how all the modules are linked together is different. Last I've read AlfaOBD doesn't fully support the 2025 trucks yet.

You cannot get access to a 2025 Ram using AlfaOBD with a bypass cable.

Search Atlantis Architecture to learn more.

Although Jimmy07 has recommended that someone try with a few adjustments and without using a bypass cable.
