Figure 8:  "With the motor in parked position, the drive wheel was installed according to the instruction sheet.  A series of holes located in the drive wheel represent 10-degree changes in wiper sweep, starting close to the center at 90 degrees.  The wiper sweep angle for the Bronco is 110 degrees, so the third hole from the center is used.  In addition, the cable must slide outward to rotate the transmission gears in the proper direction, so the hole is positioned exactly in line with the center of the cable glide and motor shaft, and as far away from the cable glide as posible.  The drive wheel retainer nut was tightened to maintain the wheel in this position.  Take care not to rotate the motor while tightening the retainer nut."
