Installing individual wires and closing the corrugated tube
Install in reverse order of removal. Note the following:
- When bundling and placing individual wires in the corrugated tube, make sure the wires are not twisted.
Note
Note the installation position of the two-part corrugated tube to the wiring harness and the position of the wiring bracket to the corrugated tube.
- The beginning of the corrugated tube -4- should be placed immediately after the clip -2- or cable tie around the wiring harness -3-.
- Make sure the two-piece corrugated tube is closed correctly over the entire length.
- After connecting both halves of the corrugated tube, wiring bracket -1- should be positioned and clipped into place according to the illustration.
- Make sure the side -arrow A- of the cable bracket connects to the last rib -arrow B- on the corrugated tube.
- Install the cable ties, wiring bracket and clips in the same positions as before removal.
Note
Make sure the connectors are installed correctly and are secure.
WARNING
Ignition must be on when connecting battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. There must not be anyone inside the vehicle when connecting the battery.
