I drilled a few holes for all of the probes and antennas that protrude thru the belly in preparation for the wiring. I installed two outside air temp probes. One came with the kit and the other came with the Dynon D100 EFIS. The Dynon unit will provide real-time density altitude. I also installed an extra anti-collision light on the belly. I probably won't install the pitot tube or the VHF antenna until just before completion to avoid banging into them during construction.
FYI: I used a set of step drills (or Uni-bits) that worked great for drilling these larger holes in the thin metal. Much faster than constantly changing bit sizes.
