I got the coax cable and SafeAire1 pitot/AOA line kit yesterday. However, I spent quite bit time in the garage, but felt not much being done. Most of the time was spent on either re-doing the left wing wiring (from bushing to conduit), and playing with how I will route the pitot static line and AOA line to wing root.
Since I have the coax cable (RG400), I route it through conduit on both wings. The left wing will have marker antenna, right wing will have VOR antenna. I didn't have to use the string to pull the cable, just inserted the cable from one end, it will go through the conduit since it has quite rigidity.
I then hand bend the aluminum tubing from the pitot tube, and flared them for the SafeAir1 pitot line kit. I like the kit a lot, it made the routing much easier, especially you need try different rounting which required connecting/disconnecting a few times. I finally decided on routing the lines under the aileron bellcrank. I had to fabricate an angle to maitence the clearance between the pitot/AOA lines and the bellcrank. I got about 1/4" clearance between them. Since the line itself has some rigidity, the clearance should be enough. If needed, I can use some proseal later on to add more constraint to the pitot lines.

Pitot and AOA lines are laid out
I inserted an smaller snap bushing in to the big one I originally planned for wiring, and routed the pitot line like this
The left aileron bell crank bushing is greased for final installation
Pitot and AOA line from the probe are flared
Fittings are tightened to the pitot and AOA tubes
Aluminum tubes are coupled to the plastic lines. I had to switch the AOA and Pitot lines. The green line is the pitot, blue is AOA
I fabricated a bracket to route the lines underneath the bell crank
Here is what it looks like around pitot tube area
