cluster transformation from a 97 to 95

i'm a newbee, just got a 95 240sx(base), with no cluster and most interior. now i recover most of the interior, except for the cluster. my friend has a 97 240sx SE cluster with the white gauges and i want to put it in my 95 240sx. now the connectors are not the same, so i do want to rewire the cluster from a 97 to 95. the only problem is that i dont know what any of the wire are for, since my car didn't come with one.
