[QUOTE="Moody, post: 636589, member: 33592"] Hi All, For intermittent wiper, I used simple wiring order.. The 12v out from delay relay triggers pin 85 of the bosch relay and 86 is grounded with pin 31 of the wiper motor..This connects pin 87 to motor pin 53 for low speed.. When motor starts moving , pin 31b gives + 12 V signal that is used for triggering another Bosch relay in which pin 30 is connected to pin 86 for ground. Positive 12 v from 31b is supplied to pin 85 of this second relay connecting pin 30 to pin 87 thereby giving negative signal to internittent relay 31b or signal pin....that instantly stops the wipers for an intermittent cycle at the park position until the relay again starts for another new cycle and on...
