Antenna and overhead wiring

I installed the temperature probe on the left wing just behind the inspection panel:

I also inserted the insulation for the firewall passthrus. Some wires may still need to move back and forth to adjust their firewall-forward length (like the O2 sensor), so I didn't apply the sealant to it just yet.

We secured the coax cables and static tubing in the tailcone:

and then connected the pitch trim servo wires:

After fixing the cabin cover forward conduit entrances, I ran coax cable for all the GPS and XM antennas, first just to get rough lengths cut out, then actually terminated them:

For the yaw trim motor, I finally decided to mount it in the tailcone using springs connected to the rudder cables - somewhat similar to what others have done, but with a smaller Actuonix P16-100-256-12-P motor (I considered using a Ray-Allen T3-12A, but that was weaker, the same weight, lower throw, and significantly more expensive). For that, I finally ran the yaw trim position all the way to the tailcone (including some annoying surgery to add those 4 pins to the subpanel CPC):

After some cabin cover work to clear the conduit entrances and attach the switch pod, I finally routed the overhead wires up through the conduits and into the overhead console.

On the next post, I'll terminate the overhead wiring.
