Hi Alex, ECM should be located under the hood on the left (drivers) side of the engine compartment. It's to the rear of the radiator mounted down low and may have a black plastic cover over it. If you look over the radiator support straight down you should find it no problem.
Hope this helps!

It's under the hood mounted close to the PS pump and radiator fan shroud. There are big plastic covers around it, but it is not underneath the big fuse center that is located close to it. It is further down.
