That will work, but it's not the right way to do it. You have to include the cluster as well. It'll run and drive, but it will read the wrong VIN number whenever you plug the car into any sort of software. I don't remember if it'll work without any coding, I'm sure a lot of things will need to get sorted out. I had to change VIN numbers in a few of the modules to get it to start. It's been two years since I did the swap.
The proper way is to get your factory CAS matched to the donor DME, which requires a special tool and software. It can't be done through WinKFP or anything like that. I had to pay for someone else to do it.
The entire swap will require coding, I ended up creating a custom VO specifically for my wagon and coding all the modules to factory default using my custom VO.
