I believe you will either have to do a harness swap or add some wires to the existing harness. There will be several differences on the engine side of the harness. One being the individual ignition coils that were added in 07. Not sure about additional sensors like on the 2.4 engine. Unless you’re going to try tuning and modding the engine, it would be easier to stick with the original ecm. In that case it might be worth looking into just doing a 2.4 swap. I was just reading on someone’s swap and as long as you’re ok messing around with the wiring, it’s doable.
