Control Unit
On 260E and 300E models, control unit is mounted under left side of instrument panel. On all others, control unit is located behind passenger kick panel. The control unit compares actual and set speed. If speeds differ, the control unit activates the control motor to attain desired speed. See Fig 1 . The control unit is fitted with a replacable reference resistor which allows specifications to differ between various models while allowing utilization of the same control unit for all models.
