A vehicle window wiper interfacing arrangement for interconnecting a window wiper function switch, a wiper motor controller, and an auto-delay controller to permit a water drop sensor to control a window wiper delay time when a window wiper system is operated in an AUTO-DELAY mode. The auto-delay controller outputs three wiper function signals, namely OFF, LOW speed and WASH to the wiper motor controller via a single bi-directional multiplexed line. The wiper motor controller outputs a wiper position signal to the auto-delay controller via the same bi-directional multiplexed line for use by a control program to determine a proper wiper delay time period.
