I did some more wire tidying. Seems to be never-ending, and I though the wiring would take no time.
Picture 1 shows how many cables now pass from the floor (around the Fuel Transducer) up through the Instrument Panel Shelf.
Picture 2 shows the Magnetometer plug and associated wiring, cable tied. I still have to finish the static line on the starboard (upper in the picture) side.
Picture 3. A bodge here. I had forgotten to pass some cables through the small snap bushing. To fix this would require pulling all of the wires back out of the 9-pin D-sub plug, which I felt would cause more problems than it would fix. I don't think my cables will chafe, but something else to show Tim, I guess.
