I've read a number of threads on wiper motor replacement but am not getting the answer I need. My original motor has one contact tab coming off the back of the gear case. The rebuilt Cardone wiper motor does not have this contact tab. I took the cover off, and the tab connects to a contact switch that opens and closes as the gear assembly turns. Is this needed for anything (example: park circuit)? It does not appear to have been connected, but this has had a couple of owners that didn't do very good repair work. The shop manual shows a ground wire that is seperate from the 4 prong plug. I am assuming the ground wire is the brass strap that connects from the bracket to one of the motor mounting bolts. Working under the dash is not allot of fun, so I want to make sure I have this right before I button it up. Any help is greatly appreciated.

According to the schematic, it looks to be a ground to me. I have been known to be wrong before.

Thanks for the schematic, it's much better than what I had. It looks like the lower right cover bolt grounds to the gear box. The gear box is in turn grounded to the wiper mounting bracket which bolts to the frame. Without confirmation on whether or not the terminal gets grounded, I am going to try it without, and see if everything functions ok. If not, I will try running a second ground. Wish me luck
