I know this has been solved here. But, I cannot find the info. I have a 98. 5 with the speedo,voltage andfuel gauges working. The oil,temp and tach is not. I have cleaned the contacts behind the cluster checked the pcm for grounding issues. But, it seems to be something simple if only half of the gauges are working. Do those sets of gauges work off the same wiring harness in the back and if so which side r/l runs the gauges that work? Thanks Damon
