NOTE : Before you tighten the clamps, adjust the wire harness to get the
____ 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 4207KS in position on the engine.
(3) Connect the electrical connector 450VC-A to the core junction box.
(4) Put the two clamps (10) on the harness 4207KS. Attach the clamps to the pylon with the bolts (5).
(5) Put the harness 4207KS into the thermal blanket (30) and (25), as required.
(6) Use a new piece of lacing and tying tape (Material No. CP8003) at each eyelet set. Tie the lacing and tying tape (Material No. CP8003) in a square knot.
NOTE : Do not tighten the lacing and tying tape (Material No. CP8003)
____ too much. There must be a clearance between the thermal blanket flaps.
