The TCM is not coded but obviously the shift programs are different so you'll have to swap that too. The engine wiring harnesses are designed to be modular so you'll unplug one from the under hood fuse box and move it with the other car with the engine. The other issue you might run into is the front and rear SAM (signal aquisition modules) if the optional equipment is different between the 2 cars (sunroof, power seats etc). You'll probably be better off swapping those too. Have STAR or icarsoft on hand. The wagon will take on the CDIs odometer reading and keys.

Great info here, thanks. If I can get away without changing the harness under the dash, that would be great. I think the only thing that may be different between the two cars is heated seats. The CDI does NOT have them. If the wagon does, I might have a problem. However, if it does have modular architecture, heated seats may just be plug-and-play.
