Wire harness

[69 coronet]

I have a 1969 coronet rt with a non rallye cluster and want to switch to a rallye cluster. Can I use the same dash harness and if so how. Some of the plugs are different. How can I make it work. Thx

From what I understand is the whole dash frame and wiring harness have to be replaced with the rallye set up. Jim
