Install the new motor onto the bracket but leave the drive crank oft temporarily. Connect the wiring and operate the wiper motor for about one minute and then turn it oft. The motor will stop in its park position. Now install the drive crank, aligning it with the mark on the bracket. Connect the linkage and install the assembly into the car. Install the wiper blades, aligning the matching marks made earlier.
