The listing of electrical wiring diagrams is shown on Figure 6-6. These diagrams key with the customized wiring drawings provided with the airplane. The drawings enable the test cell designer to design a control system and identify wiring from the control console to the EBU interface.
Electrical harness connections between the EBU and strut are grouped at two principal locations:
.
Left side, top of fan case
.
Mid spar, strut area for "core" connectors Additional connectors are located at:
.
