Yes, option code CD4, intermittent wipers. According to ordering procedures it was mandatory fitment with 308 and 4spd on Holden and Kingswood from late HJ. Yet to confirm if this carried through to HX or if it became optional again. I suspect it was mandatory in HJ as the dwell was part of the wiring harness, but in HX/HZ it became a patch harness so it may have been an option.
