That's a tough call. No one really knows. When I had my 04' 35, I bought a cluster not knowing it was a tech. Installed it and it worked, but the orange cruise light was always on because it was a tech cluster and it couldn't find the module for the laser cruise. I sold it to another member that had an '03 45 tech and it worked fine. I bought a non tech later with the right part # and it worked just fine. In my opinion, if you match up tech with tech, I feel it would work just fine, but then again, no one really knows.
