As I connect wires to the panel I'm making adjustments so the panel can be removed. 1. The USB power wires need a connector. 2. I installed the key switch. I also left a 12 Volt wire here for future use. It comes from #15 CM. 3. I left a 5V wire available on he left side behind the key. 4. I ran an extra 12V wire down the center of the fuselage to the cargo area. It can be used for dome lights. It comes from #15 of CM.
