Tonight I went back to some wiring loose ends as I will need to get the wiring done and the top skin on before I can start working on the cowling. I picked the easiest one and jumped in, and that was choosing the location, drilling the hole, deburring holes, applying the label, and installing the music input port for the pilot's listening pleasure. Bluetooth technology has likely made this port obsolete by now, but if needed, it's there. The entire process took a little longer as I was hanging over/in awkwardly while working, but the remaining wiring list is one item shorter tonight.
