I put the AP servo in the left wing to avoid running wire wing to wing for trim, but this required a different servo bracket, as Garmin's only fits in the Right, and you still need to run the CanBus. I'm not going to say that it's a better way to do it - costs more for the extra bracket and the installation instructions have to be read as if in a mirror...but it works fine. Stein helped with bracket. I'm pretty sure you can run the trim in the either wing as well.
