Completed wiring from breakers to panel switches for such things as lighting, fuel pump, pitot heat, etc.
Went back and began making CAN Bus connections in LRU connectors where I left them out initially in order to shorten the bus wiring once all the connectors were completed and in the panel. Was able to shorted a few wires, but others appeared to be as short as I felt appropriate in keeping with adequate service loops and being able to maintain LRUs and wiring in the future. Completed the CAN Bus connections on 3 additional LRUs
Recognized that the GTR 20 radio as installed in the shelf behind PFD-1 does not have adequate space to install/remove the wiring D-sub connector. Removed the GTR 20 and switched the mounting brackets from the ends of the radio to the sides. This will provide room for the wiring at the back of the radio, so long as it sits below the sub-pane, which I think it will. Will also need to install 3 new nut plates to hold one side (can re-use the originally installed nut plates for the other side.)
