Starting this thread to document my new interval wiper design. This will use the stock 2 speed wiper switch with a programable delay relay. The Lo speed position will be the programable delay, hi speed will be high speed. First step was to make the test setup. I used a nissan wiper motor since it was $20 vs the very expensive FJ40 wiper motor. Nissan switched their wipers on the ground side like the FJ40 wipers do so it is a suitable stand in. The wire colors I used are not accurate but they work. I documented the actual connector wire colors and positions on the rear side (the side the wires come out of). I also had to make a short conversion harness to transition from the 6 place connector on the motor to the 4 place windshield connector.
