1. Attached a mini-jack pigtail to the existing airframe wires, to connect the aileron trim servo. The plug and jack have reversible polarity so I can swap them around if I need to later.
2. Fabricated two pairs of copper bus bars for the Main Bus circuit breakers (no photo).
3. Cut and filed notches in the main panel support structure at the four locations where clearance is an issue with various avionics items. Also removed one nutplate and replaced it with a stubby nutplate, oriented 90 degrees to the original one, This will allow the EFIS screen to be mounted.
4. Fabricated one of the two attach angles that will support the main panel avionics. Began fabricating the second one. I had to notch out the edge of the left side sub-panel to make everything work.
