01 wrangler gauges do not work..

I am working on a friends 2001 wrangler.The gauges are all inop. and the check engine light and fuel light will come on.I scanned the pcm and it has not dtc's.I removed the instrument cluster and bent the pins and added electrical grease.I check for power and ground and I have both at the cluster.I performed the cluster test and all of the gauges swept correctly.I checked the violet and yellow wire fronm pin 30 at the pcm to the cluster.it had .3 ohms.Checked it for short to ground and power all is ok.My question is....How can you tell if it is the pcm or can it still be the cluster even though all the gauges swept?

thank you.....
