I discovered that the EFII controller needs a continuous power source for the real time clock. Today's task was to route the new wire from the battery to the controller wiring. The wire was routed through existing conduit, connected and tie wrapped in the tailcone.
The wire was then routed along the left side wiring to the bus manager.
The side panel and flap torque tube cover were reinstalled.
The interior handles were test fit but still need additional trimming.
