It should only be the wiper/washer combo switch/stalk (has relay/controller built-in fer the intermittent part). You'll probably have to git the entire turn signal/cruise/wiper setup as I'm not sure how easy it is to separate. The wires fer all the steering column harness is bound together. The wiper switch is attached with 2 screws.

The wiper motor is the same whether you have the basic or intermittent setup. <img src="/forums/images/graemlins/smile.gif" alt="" />

Just be careful when yer working with the airbag clock spring... <img src="/forums/images/graemlins/wink.gif" alt="" />
