wiper motor wont "park"?? 74 duster

found a digital copy here on site somewhere. Brown wire went to washer pump. Still cant get wipers to "park". I found a checklist that someone on site copied.

I will try this. I tried to run a ground from the wiper motor to the neg battery post and also ran one from the wiper switch to dash frame-wasnt good as battery because I was just pressing it against bare metal. But still shouldve done something. Time to go test between the rain drops. Anyone with any ideas?
