I put in the new conduit systems in both wings. I used 1/2" drip mist tubing (5/8" OD). The 3/4" bushings were a bit too tight. I used the Unibit to enlarge the interior hole of the bushing. This still didn't work - there was too much friction to pull the conduit through. I ended up pulling the conduit, then installing "split" bushings. This worked quite well.
I pulled most of the wire into the left wing. I didn't have any #14 wire for the lights, so I had to defer this until wire arrives from ACS.
