    The Knock Sensor's are Located, Underneath the Intake Manifold, in the Diagram, Number #717 is the Wiring for the Knock Sensor's and Number #718 are the Sensor's.

    Thanks for your help. Havent changed it yet but seems easy enough. Now the rear end is squeaking quite a bit, figure take her in for a chassis service.
