I received the Dynon pitot tube, Nylabraid, shielded wire, screws, and connectors from Aerotronics. I installed the connectors to the light dimmer and its connector. I clamped the control cable bracket to the instrument subpanel. The air vents were installed and the black tubing was connected to the NACA vents. I screwed the marker beacon antenna in place using AN3 bolts, instead of the screws provided. I need assistance with putting the screws in.
