I think certain parts work.... I know wranglers can swap steering wheels.
hmmm... not to hyjack... maybe a good topic for another thread? I would really like to swap wheels, but only if the control buttons work as well as the air bag being able to plug right in....
I just remember a bunch of stuff from the 2008 LX refresh that didn't work in older cars because even the connectors in the harness were different not to mention different network protocols.
Now, funny enough, the tuners worked on all years all the way to 2010.
