A. Install the data entry plug assembly (1) to the fan case at Flange FC:
F Data Entry Plug Assembly ** ON A/C NOT FOR ALL
CAUTION: YOU MUST MAKE SURE THAT YOU INSTALL THE CORRECT DATA ENTRY PLUG FOR THE ENGINE. INSTALLATION OF THE INCORRECT DATA ENTRY PLUG CAN CAUSE THE ENGINE TO GIVE INCORRECT THRUST VALUES.
   (1) Remove the protective cap or bag from the data entry plug assembly.
   (2) Make sure that the engine serial number on the data entry plug backshell is correct for the engine you put it on (see the engine identification plate for the correct engine serial number).
   (3) Install the pin (9) through the data entry plug assembly connecting cable hole (8) and through the rear side of hole No. 14 located on Flange FC.
   (4) Install a new AIPC 73-22-35-80-010 COLLAR (7) on the pin and tighten it by hand.
   (5) Hold the pin (9) with a wrench in the hexagon opening.
   (6) Tighten the collar (7) in a clockwise direction until the hexagon nut is sheared off.
   (7) Discard the sheared hexagon nut.
   (8) Connect the data entry plug assembly (1) to the electronic engine control (2).
