Here is a photo of my pitot & AOA tubing and nav/strobe wires exiting the rear spar (notice the split tubing for protection). Also note how they lead right into the fabric wrapper on the diagonal airframe tube. You will also note that I used high quality weatherproof connectors for the wiring at this point, in case I ever want to remove the wings. I have folded the wings back several times with this wiring and tubing routing and it works fine without pinching or damaging anything.
