There turned out to be several switches that I failed to account for in my initial design. The AFS AOA Sport requires two switches, the CO Guardian requires a test/reset switch, the GX Pilot requires a selector for determining if it should listen to the GTN or the G3X and there are a couple of dimmers to work in there too.
I wasn't sure where to put these, since my right side 'switch panel' was exactly how I wanted it. So, at least for now, they reside on the left side along with the fuel selector. The way I see it, none of these will be switches I often use...so having them a bit out of the way seems appropriate. If I hate it, I can always move them.
The labeling was done with water slide laser paper. I've used it in the past with good results under a clear coat paint. I'll do the same in this case once they have dried for a day or so.
