The rear wiper motor is controlled by the SJB. The SJB supplies power to the rear wiper motor through circuit 411 (BK/LB) from the integrated rear wiper relay and through circuit 406 (BN/WH) from the SJB fuse 21 (10A). The multi-function switch applies ground to circuit 485 (PK/BK) for low speed wipe, or applies ground to circuit 410 (WH/OG) for intermittent wipe. The multi-function switch and the rear wiper motor is grounded through circuit 57 (BK).
