Where wires on wiper motor go

I have a 1984 Chevy Camaro that someone chopped alot of wires out of and I've managed to get it running again, my current problem is I can't figure out where the two wires on the bottom of the wiper motor are supposed to go in relation to the car wiring. I still have a plug for the top wires (washer pump I think) Would someone trace down where their bottom wires go for me? I looked in a repair manuals wiring diagram but it's not much help.
