The right controller for a 2009 would be the 2009. It's close enough to the dash that I can look at it when I need to.
In addition to the gain, it does show a bar graph of the power output, which may be useful to some.
However, seeing how the TBC is part of the truck's trailer sway control and can save you in an emergency situation, I wouldn't dare try putting in one from a different model year.
