On a second Generation, it is above the kick plate and to the left of the steering column. Remove the plastic kick panel (there's two bolts hidden behind the hood release to get that plastic panel out), then pull the steel panel above it. It might be yellow or it might not but it'[s a small plastic box affixed to the dash right above where your left ankle would normally sit. Some parts houses will try to sell you two, but (on a 99 at least) there is only one, responsible for both directionals and flasher. I had an odd double failure, the module went bad and the multi-function switch failed in such a way I had no turn signals and the left signal would illuminate with the stop lamps. I must have looked funny with my arm out the window, turning right with the left signal stuck on
