Safety Requirements
NONEProcedure
Refer to Figure.
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).
Refer to TASK 72-00-32-420-001-B00 (INSTALLATION-001) for the position on a raft or bracket of a particular clip position.
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.
For the data on the electrical connectors refer to SPM TASK 70-43-00-400-501 and SPM TASK 70-43-01-400-501.
