In order to pull the wiring harnesses from the rear to the front I had to remove the D-sub connectors on the remote transponder and remote comm/AP harnesses. I then pulled the two harnesses up to the instrument panel. I reinstalled the D-sub connectors, attached the harnesses to the various components in the tail and tied off the harnesses. I also worked on the wiring for the elevator trim and ELT. Almost finished with electrical work behind the baggage bulkhead.
