Couple days ago the cluster went nuts buzzing turning off and on etc. I did not however lose my headlights, I was driving at night. The gauges bounced up and down liek crazy then it settled then again etc. Not sure maybe a bad ground? When the indicator was on I could see the RPM needle pulsate with the blinking.

What should I be looking for a bad ground?

I found the diagrams trickster posted will help

 

Hey IroczInOz,

There should be two grounds near the steering column for the instrument cluster. They will be attached to the forward dash support frame. Let me know if you need any more info.

 

Forward dash support frame? If I can't find them I will try and trace the wires from the connectors going by the diagram

 

The metal frame piece above your knees that the dash bolts to.

 

Cool got it will check it out any dramas will get back to you.

Thanks,
Mike
