Cruise on/Off Switch




The cruise On/Off is a normally-open push-button switch that allows the driver to engage/disengage the cruise control system. When the button is On, the Light-Emitting Diode (LED) will illuminate, and voltage will be applied from the Underhood Fuse Block (UHFB) through the coil assembly (roll connector) to the ECM cruise on/off input.
