It is, however the delay wiper cars used the wiper motor with the non-concealed parking position. That wiper motor has a pin on the connector that grounds out every time the wiper motor hits the bottom of it's travel. The delay wiper circuit needs to know when the wipers are at the bottom of their travel to begin the count down to the next swipe. On the wiper motors with the concealed parking position, this pin only grounds out when the wipers hit their parked/concealed position below the windshield.
