Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling .
Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

Important: Twisted-pair or twisted-triplet wires provide an effective "shield" that helps protect sensitive electronic components from electrical interference. If the wires were covered with shielding, install new shielding.
In order to prevent electrical interference from degrading the performance of the connected components, you must maintain the proper specification when making any repairs to the twisted wires.
The following specification applies to all twisted wires except within the body harness and the PhatNoise harness:
| • | The wires must be twisted a minimum of 9 turns per 31 cm (12 in) as measured anywhere along the length of the wires. |
| • | The outside diameter of the twisted wires must not exceed 6.0 mm (0.2 in). |
| • | If a drain wires is present, the drain wire must be placed along the length of the twisted wires. |
| • | If the wires are covered with shielding, the twisted wires and the drain wire must be continuously covered by shield tape, aluminum side inward. The shield tape must be covered with tape. |
| • | The wires must be twisted a minimum of 12 turns per 31 cm (12 in) as measured anywhere along the length of the wires. |
| • | The outside diameter of the twisted wires must not exceed 6.0 mm (0.2 in). |
| • | If a drain wires is present, the drain wire must be placed along the length of the twisted wires. |
| • | If the wires are covered with shielding, the twisted wires and the drain wire must be continuously covered by shield tape, aluminum side inward. The shield tape must be covered with tape. |
| • | The wires must be twisted a minimum of 3 turns per 31 cm (12 in) as measured anywhere along the length of the wires. |
| • | If a drain wires is present, the drain wire must be placed along the length of the twisted wires. |
| • | If the wires are covered with shielding, the twisted wires and the drain wire must be continuously covered by shield tape, aluminum side inward. The shield tape must be covered with tape. |
