I left the tubing in the wing spars because there are many sharp rivet ends poking thru the spars and no way to secure the wires from bouncing around in turbulence.

I preferred the irrigation tubing over the corrugated because "fishing" a wire thru is easy. It can also be easily slit with a pocket knife if desired, and the slit stays closed; it takes quite a bit of effort to open the slit and pull a wire out. In fact in a couple of places where I needed a wire to exit I cut a little wide spot in the slit so the clamping force of the slit would not damage the wire insulation over time. Handy stuff, cheap and lightweight and easily cut or bent.

If you need to get a wire through a sealed tube, whether it's a piece of pipe or a wing spar, try this trick. Tie a wad of cotton balls to the end of a length of nylon string, then use your shop vac to pull it through the tube. Once it's through, cut the string sticking out of the shop vac and you're left with a pull cord in the tube. Always pull another pull cord through with the new wire, and you'll never have to do the vacuum trick more than once.
