dash wiring

[loader820]

Hi, I have a 1982 chev C10 and I took the cluster out and replacing it with new gauges. On the back it has a wire harness that has numbers on the black piece that connect to the gauge cluster. Does anyone knows which number goes to which gauge on the cluster.Im trying to find out which one goes to which one so that i wouldnt have to wire the whole new gauges up. I can just get the wire from the harness that plugs to the cluster
