A. Installation of the Vibration Sensor Harness Assembly (4206KS)
F Vibration Sensor Harness Assembly ** ON A/C NOT FOR ALL
NOTE: When using fiberglass clamps on the engine core harnesses, do as follows: Wrap fiberglass adhesive tape (Material No.CP2208) around the harness(es) to make sure that the clamps do not move when they are installed. Wrap only the locations where the clamps are being installed.
NOTE: Before you tighten the clamps, adjust the wire harness to get maximum clearance between the harness and the other structures on the engine. Make sure that the harness will not touch other structures.
   (1) Remove the blanking caps from the electrical connectors.
   (2) Put the harness 4206KS in position on the engine.
   (3) Connect the electrical connector 457VC-A to the core junction box.
   (4) Put the two clamps (10) on the harness 4206KS. Attach the clamps to the pylon with the bolts (5).
   (5) Put the harness into the clamp (20) attached to the bracket at station 233. Make sure the reference marker is correctly aligned. Install the bolt (15).
NOTE: The Installation Reference Markers are fiberglass tape on the harnesses.
   (6) Put the harness into the clamp (35) and install the bolt (15).
   (7) Put the harness into the clamp (40) attached to the bracket at station 233. Install the bolt (15).
   (8) Connect the electrical connector 4003EV-A to the TRF Vibration Sensor (4003EV).
   (9) Make sure that the harness 4206KS is correctly installed on the engine.
   (10) TORQUE the bolts (15) to between 25 and 20 lbf.in (0.28 and 0.23 m.daN ) T.
