Procedure

1. Refer to Figure.
2. 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 the correct installation of the different harnesses and prevent too much strain on the electrical connectors. It will also give the necessary drip loops (the drip loop makes sure moisture or fluids do not go into the electrical connector).
3. Refer to TASK 72-00-32-420-001 for the position on a raft or bracket of a particular clip position.
4. 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 numbers) refer to the IPC (70-40-10). If the harness diameter is between two of the clips in the range, use the larger clip. When you do this use CoMat 02-148 ADHESIVE TAPE (ELECTRICAL) to increase the harness diameter.
5. Do not remove the special plastic caps from the electrical connectors and receptacles until immediately before they are installed. This will give protection from unwanted fluids or materials.
6. For the data on the electrical connectors refer to the SPM TASK 70-43-00-400-501 and the SPM TASK 70-43-01-400-501.
1. Refer to Figure, Figure and Figure.
2. Temporarily attach the IDG cable connector to a safe position on the LP compressor/intermediate case with CoMat 06-086 TIES.
3. Install the bolts, the washers, the clips and the nuts to attach the cables to the brackets at the clip positions 0883 to 0888. Do not tighten the nuts at this step.
4. WARNING
  WHEN YOU USE CoMat 01-002 SOLVENT, DELETED. YOU MUST USE THE NECESSARY PROTECTIVE CLOTHING. DO NOT GET SOLVENT ON YOUR SKIN OR IN YOUR EYES. YOU MUST NOT SMOKE WHEN YOU USE THE SOLVENT AS THE VAPOR CHANGES AND BECOMES TOXIC.

5. 1. Make sure each harness wire bundle breakout curves smoothly from its primary harness. It must go to the component to which it attaches and not across the primary harness.
  2. If the primary harness and the wire bundle breakout touch each other you must attach them together. Both harness bundles must not move in relation to each other. Refer to Step.
6. 1. If one harness goes across or it is parallel with a different harness (and they can touch) you must attach them together. Each harness must not move in relation to each other. Refer to Step.
1. Attach the wire bundle breakout to the primary harness with CoMat 02-159 LACING TAPE to prevent movement of them in relation to each other.
2. Attach the parallel harnesses and those which go across each other together. If it is necessary wrap CoMat 02-148 ADHESIVE TAPE (ELECTRICAL) around the harness to prevent abrasion. Then attach the harnesses together with the lacing tape.
1. Refer to Figure.
2. Make sure that all the applicable connectors, backshells and cable clamps are secure.
3. Make sure that all the applicable backshells and cable clamps are safetied with CoMat 02-126 LOCKWIRE. Refer to the SPM TASK 70-42-05-400-501.
