Procedure

    1. SUBTASK 78-32-77-430-051 Assemble the Right C-Duct Electrical Harness

    1. Refer to Figure, Figure and Figure.

      2. Assemble the 902P plug (01-210) on the wire.

      1. Get the contact insertion tool for the wire size to be installed. Refer to Figure.

      2. CAUTION

        THE INSERTION TOOL MUST BE PARALLEL TO THE AXIS OF THE CONNECTOR WHEN THE WIRES ARE INSTALLED TO PREVENT INTERNAL DAMAGE TO THE CONNECTOR.

        Put the contacts (01-250) in to the correct positions by hand. After the contacts are started in to the connector, fully install them with the insertion tool.

      3. Push on the contact from the front of the connector to make sure that it has been correctly inserted. The contact is correctly inserted when there is no rearward movement of the contact within the connector.

      4. Move the boot (01-300) along the wire bundle toward the connector until it touches the rear grommet.

      5. Move the connector backshell along the wire bundle and turn it on to the connector shell. Tighten the backshell by hand plus 1/8 to 1/4 turn with the connector pliers.

      6. Wrap the wire bundle at the strain relief clamp location with CoMat 02-177 MASKING TAPE (GLASS CLOTH) until there is enough tape to give a tight hold on the wire bundle when the strain relief clamp is installed on the backshell.

      7. Install the strain relief clamp on the backshell with the screw. Torque the screws to between 12 and 15 lbfin (1 and 2 Nm). Safety the screws with CoMat 02-176 LOCKWIRE.

      8. Do a continuity check of the wire harness to make sure that it has been assembled correctly. Refer to Testing-001 TASK 78-32-77-700-301.

      3. Assemble the 904P plug (01-270) on the wire.

      1. Get the contact insertion tool for the wire size to be installed. Refer to Figure.

      2. CAUTION

        THE INSERTION TOOL MUST BE PARALLEL TO THE AXIS OF THE CONNECTOR WHEN THE WIRES ARE INSTALLED TO PREVENT INTERNAL DAMAGE TO THE CONNECTOR.

        Put the contacts (01-250) in to the correct positions by hand. After the contacts are started in to the connector, fully install them with the insertion tool.

      3. Push on the contact from the front of the connector to make sure that it has been correctly inserted. The contact is correctly inserted when there is no rearward movement of the contact within the connector.

      4. Move the boot (01-290) along the wire bundle toward the connector until it touches the rear grommet.

      5. Move the connector backshell along the wire bundle and turn it on to the connector shell. Tighten the backshell by hand plus 1/8 to 1/4 turn with the connector pliers.

      6. Wrap the wire bundle at the strain relief clamp location with the CoMat 02-177 MASKING TAPE (GLASS CLOTH) until there is enough tape to give a tight hold on the wire bundle when the strain relief clamp is installed on the backshell.

      7. Install the strain relief clamp on to the backshell with the screws. Torque the screws to between 12 and 15 lbfin (1 and 2 Nm). Safety the screws with the CoMat 02-176 LOCKWIRE.

      8. Do a continuity check of the wire harness to make sure that it has been assembled correctly. Refer to Testing-001 TASK 78-32-77-700-301.

      4. Assemble the 900J receptacle (01-240) on the wire.

      1. Get the contact insertion tool for the wire size to be installed. Refer to Figure.

      2. CAUTION

        THE INSERTION TOOL MUST BE PARALLEL TO THE AXIS OF THE CONNECTOR WHEN THE WIRES ARE INSTALLED TO PREVENT INTERNAL DAMAGE TO THE CONNECTOR.

        Put the contacts (01-220) in to the correct positions by hand. After the contacts are started in to the connector, fully install them with the insertion tool.

      3. Push on the contact from the front of the connector to make sure that it has been correctly inserted. The contact is correctly inserted when there is no rearward movement of the contact within the connector.

      4. Move the boot (01-300) along the wire bundle toward the connector until it touches the rear grommet.
