It doesn't say anything about the idiot light, but if it did I would bet it would say take it to the dealer.
I'm sorry I left my book at home today and I am out of town untill the weekend but as far as I remember it is a yellow plug/wire harness thing under the steering wheel. I think the 94 will have a panel and the 98 should just be under there somewhere.
The thing is, if it has driver and passanger side airbags you would half to do both I'd think. On a 98 you have to remove the glove box to get to the yellow airbag plug for the passenger's side and I think the 94 is just under the dash on that side.
So for both of them just unplug it and wait a wehile then plug it back in.
Hope this helps.
I'll check the book this weekend and see if there is anything I missed.
