I spent quite a while organizing all the various small projects that need to be done before I mount the tail, and categorizing them further into projects that would be best to accomplish before I mount the landing gear.
I also continued fabricating and began installing the two right map pockets, and tried to figure out a location for plug/mount for the flexible, LED map light. I temporarily installed the front seat to get an idea of geometry and ergonomics issues.
My friend Jim came by and suggested I actually mount it inside the upper-right map pocket (on what is the right armrest). It looks like this might actually keep it out of the way when not in use. I have to examine whether the wires would protrude too much from under the armrest, and interfere with the passenger's right foot. [Superseded.]
I also adjusted the tail wires to their final lengths, and took care of a few more wiring details in the baggage compartment.
