N. Electrical Harness Installation Procedure
F Electrical Harness Installation Procedure ** ON A/C NOT FOR ALL
   (1) During the installation procedure make sure the harnesses are held temporarily along their different lengths. Always install the datum clip positions when you install each electrical connector. This will give correct installation of the different harnesses, prevent too much strain on the electrical connectors and give the necessary drip loops (the drip loop makes sure moisture or fluids do not go in to the electrical connector).
   (2) Because of the differences between the harness diameters, the specified clip could be too large or too small. You can use a clip from a range of six clips that have the same part number. If the harness diameter is between two of the clips in the range, use the larger clip. When you do this use V02-148adhesive tape (electrical) to increase the harness diameter.
   (3) For the data on the connection of electrical connectors refer to (Ref. AMM TASK 70-23-15-912-010).

P. Measure the Harness Clearances and Examine the Harness Route
F Examine the Harness Routing ** ON A/C NOT FOR ALL
   (1) Measure the clearance between all the different harnesses and the engine parts.
     (a) The general clearance must be a minimum of 0.250 in. (6.35 mm).
     (b) A minimum clearance of 0.100 in. (2.54 mm) is necessary between the EEC harness, the IDG oil cooler and the tubes in the area shown in.
     (c) To check the clearance, push the harness with a light pressure of the thumb then release. The harness must spring back and give the minimum cleareance. The harness must not move throught the adjacent clips.
     (d) The harness can touch the smooth parts of the brackets if the harness is clipped to them. The harness must be held so there is no movement between the harness and the bracket.
   (2) Adjust the harness (if necessary) to get the minimum clearance.
   (3) TORQUE the clip position nut or bolt to between 45 and 36 lbf.in (0.51 and 0.41 m.daN ) T. (Ref. AMM TASK 70-23-11-911-013)
