I was feeling pretty good about my wiring, right up until I hooked up the intercom. All of the audio is just really weak. I did a little bit of troubleshooting before tabling that problem, pending more research. I installed the aft dome light, which will be able to serve either the baggage area or the back seat. When I installed the tab to support that dome light, I wasn’t planning on covering the ceiling the way that I did. In retrospect, I would have rather had the tab on the lower tangent of the tubes, rather than the upper. As it is now, the base of the light is under the fabric.
I also spent a little while pulling off the masking tapes from the last load of white paint parts.
