Can anybody help me find the pin out for an ACDelco 22873153 wiper motor? The OE fitment is C7 Corvette. The wiper motor only has a 5 pin connector.

I have successfully identified the Ground, Slow, and Fast pins. One of the other pins definitely controls Park functionality, but I can't quite get the whole thing working correctly and I believe the unidentified 5th pins holds the answer! Thank you in advance.

That could be where I have been going wrong...I have been assuming that the park needs 12v applied but maybe I need to ground the park pin. Any chance that you could post or link the drawing that you're referring to?
