wiper problems

I've just replaced my wiper linkage and obviously botched the reassembly because the wipers want to move down from the parked position. Does anybody know how to figure out the proper positions of the motor and linkage when it all goes back together?

Nothing on Interwebs like on youtube?

This might help? https://www.youtube.com/watch?v=6Y6FAsvPwd8
