These directions got me through it (posted by ZX1100F1)
FIRST: Disconnect the negative battery cable
On the back side of the steering wheel, there are 2 access holes which directs the tool to the release retainer. The middle holes are for the module removal. Using a 3-4 mm wire or 4 mm allen type wrench, push the retainer inward and slightly upward through the access hole. Repeat the step for the other access hole.
You will have to turn the steering wheel to gain access to each hole.
Parts 3 and 4 are trim pieces, part 9 is the airbag.
