70 swinger rallye cluster diagram

Are you talking about the actual cluster or the under dash harness TO the cluster?

The diagrams you posted are available over at MyMopar. while somewhat useful they are not complete and sometimes misleading. They do not show all connectors, etc. The harness to the cluster may be the same, that is, at least the wire colors to the cluster.

Have you seen this thread?
