In the beginning I had planed to use a simple bent tube. Moving along on the project I went with a Dynon EFIS and since it was available decided to use the AOA Pitot instead of the simple tube. Now that I'm ready to plumb the Pitot tube I'm going to pull the wiring out of one of the two the grommeted holes, the other already being used for Pitot, and use those holes for the second air source. However, my wires need to go back in. I'm wondering how some of you might do this? Pictures would be nice. My first thought is to use a wire tie or string wrap a piece of tubing along the back side of one of the large rib lightening holes.
