Drill 7/8" hole in F-705 bulkhead from the baggage compartment floor for the conduit that will hold the shielded cables from the wings for the strobe lights. Time consuming job because acess is not very good and I wanted to make sure I drilled the hole in the proper location. Put the corrugated conduit through the hole and install fish line. The conduit will be trimed both ends at a later time.
