Section 98 (Cruise Control Systems): Cable: Operation
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
This cable causes the throttle control linkage to open or close the throttle valve in response to movement of the vacuum servo diaphragm.
