• Make sure the steering switch harness is correctly routed above the center of the driver air bag module inflator (1) as shown (B), and NOT incorrectly routed across the driver air bag module inflator as shown (A).
• Be careful not to damage or pinch the harness while installing.
• Tighten the driver air bag module bolts after centering the holes between the driver air bag module and the steering wheel horn contact bracket. If the holes are misaligned, the bolt threads may become damaged and the module will not install securely.
