The transmission contains the park switch which puts the blades at the bottom of the windshield when the wiper control is set to off. Aug 24, 2003. Messages: 108. The 69 - 71 electric wiper system uses a three wire switch and the 72 and up uses a 5 wire switch. If you have a copy of the 1971 edition of SM-1046 there's a very good diagram there and several paragraphs on troubleshooting that switch and motor. Red is high, green is low and black is park. Connect the black wire from the motor to the fourth blade on the wiper switch terminal, which is the ground wire connection. Connect the white, red or green wire from the wiper motor to the second blade on the wiper switch terminal. This is the power wire connection. Windshield wiper motor wiring diagram
