You should be able to release the individual connectors in the connection block so that you can avoid destroying the block. Then you can reposition the wires in the block according to your needs. Check out the link below for tips and terminals.So I’ve been pouring through old wiring diagrams, and today will try to modify the gpz harness to plug into the Connie harness and have everything work. when successful I will post the wires that had to be changed to make an 85 GPZ900r gauge cluster work on a post 94 Concours. All the colors are the same for the same function, but the location within the 9 pin block are all wrong. So cutting and replacing the junction block is required.
