1. On Deville and Fleetwood, remove the left lower sound insulator. On Eldorado and Seville, remove the left side sound insulator.
2. Remove the Connector Position Assurance (CPA) and detach the yellow 2-way connector at the base of the steering column.

2. Remove the bolts/screws from the back of the steering wheel and remove the inflator module.
3. Remove the horn contact by pushing slightly and twisting counterclockwise. Detach the electrical connectors from the inflator module.

CAUTION

When carrying a live inflator module, make sure that the bag and trim cover are pointed away from you. Never carry the inflator module by the wires or connector on the underside of the module. In case of accidental deployment, the bag will then deploy with minimal chance of injury. When placing a live inflator module on a bench or other surface, always face the bag and trim cover up, away from the surface.

4. Remove the steering column shaft nut. If not already marked, mark the steering wheel and steering column shaft to ensure proper alignment during installation.
5. Remove the steering wheel using steering wheel puller J-1859-03 or equivalent.

6. Feed the SIR coil assembly lead through the slot in the steering wheel. Align the mark on the steering wheel with the mark on the steering column shaft and install the steering wheel.
7. Install the steering column shaft nut and tighten to 30 ft. lbs. (41 Nm).
8. Install the horn contact to the steering column.
9. Attach the electrical connectors to the inflator module. Position the inflator module on the steering wheel taking care to ensure no wires are pinched.
10. Install the inflator module retaining bolts/screws and tighten to 27 inch lbs. (3 Nm).
11. Enable the SIR system as follows:
    1. Connect the yellow 2-way connector at the base of the steering column and install the CPA.
    2. On Deville and Fleetwood, install the left lower sound insulator. On Eldorado and Seville, install the left side sound insulator.
