Where is this thing

[Rodimus_Prime]

So I have a Turbotweak chip coming in the next few days and I'm wondering where it goes in.

I think its somewhere under the dash on passenger side, is there a how to on this someplace?

The ECM is pretty much on the other side of the dash pouch. You'll need to be on your back looking up once you take that plastic trim piece off. You'll see the ECM up there. Unplug the harness and unbolt it. There will be a little door on the ECM you'll need to take off and the chip is under there. Just remember to disconnect the battery before you start. It's actually pretty easy from start to finish.
