I procrastinated a bit on how to run the tail light wire and the electric trim, settled on running flexible conduit through the rear bulkheads and silastic around the entrance holes in case of any vibration. Time to move onto the side steps, mark the holes in the right step, drill the holes into the fuselage, trim a small bit of excess off the step to match the contour of the fuselage as best I could. File, scotchbrite the edges after rounding smooth, mount and drill the mounting holes through the plastic to the rib. Repeat for the left side, steps done.
