Although I was able to enlarge a couple of holes with tools I had on hand, there was no such luck with the holes for the wing spar pin switch on both sides. After consulting with VAF and the Facebook group, I bought about $100 worth of tools, but the step bit wasn't a hex, so I trudged to Northern Tool to get one of those. Then I successfully drilled the holes in the F-1204B on each side to 5/16 and installed the switch on the right side. The instruction figure for the left side shows bushings in place so I need to find out what number bushing before installing that one as it has a wire from the fuel tank (which I removed). I riveted in two ES-00301 (zip tie holder) to the F-01223-L-1 and F-01223-R-1 ribs under the baggage floor which was a major pain in the neck to get to. I routed the trim wire and AOA tube WH-P30-1 to the front of the plane (the AOA tube exited out the side of the fuse, and loosely zip tied the trim wires to the n F-12103-1.
