Rally dash redo

@4spdragtop
Maybe the way to do this without driving yourself crazy is work from the harness that needs repair.
Is it a '67 fastback?
Lay that one out on a bench or even better a board.
Tag the bad terminals or whatever needs repairs or replacing.
Then go over to your '68 harness and diagram. See if that one wire or circuit is the same. If it is transfer it. (Unrwap the harness tape, etc)
Do all that you'ld like to replace.
Then any bad ones that aren't one to one swaps will need to be repaired or spliced.
