For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Note. The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle. Since Chrysler LLC vehicles use only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.
