Use Guide
- Match the M18X1.5 thread and 24mm spanner size against the old switch before ordering
- Isolate the battery, remove the old switch from the transmission housing, and install the replacement with correct orientation
- Test the reverse light activation when shifting into reverse before releasing the vehicle
- If the light still fails, check the reverse light bulb, fuse, and gear position sensor before condemning the switch
