Today I received the 5-conductor wire for the elevator trim, so I bundled it with the others, taped the bundle to the pull-string already in the conduit and pulled them all through. I then fed the strobe and nav light wires through the grommets in the two aft bulkheads, and installed a hole edge grommet in one of the lightening holes in the horizontal stabilizer, where the trim wire will pass through. (It will also get wrapped with spiral-wrap in that area.)
