2019 RAM 3500 Aisin Trans - Unlock Cable - MM3 Install

[Bigdodge06]

Okay, guys, it might be something that has been discussed, but with three different styles of unlock cables for the 19 ECM, which cable, or do I even need a cable to install my MM3 onto my truck?

I didn't want to try it and mess anything up, so I figured I'd ask some knowledgeable guys first.

Thanks in advance for your help.

No one has tried to tune a 19 RAM 6.7L without the unlock cable.

I've heard something about it, and I would only need an unlock cable if my security module were bad.

If I have to have one, I dont want to try and flash the ECM without one of the three styles unlock cables.

Which one works the best?

I also know that I will leave it under the dash if I have to get a cable.

If Anyone has tuned a 19 with an MM3, let me know what you used and how you went about doing it.

Thanks again.

In advance, let's pick some brains!
