Warning
This procedure retrofits a touch horn steering yoke with a mechanical horn steering yoke. DO NOT reinstall the existing driver airbag, as it is incompatible with the mechanical horn steering yoke. A new airbag that is compatible with the mechanical horn steering yoke must be installed. A Toolbox routine performed later in the procedure will request the removed and installed airbag part numbers to verify compatibility.
