Rally dash harness vs standard dash

Hey all, how do you tell the difference between a wiring harness from a rally dash vs one from a standard dash? I'm putting my '67 Barracuda back together and I can't tell which harness came out of it. I've got a bunch of harnesses here from number of different A bodies but I'm not sure which to use. Are there any noticeable differences to look for? Also I have a console with 4 speed so I need to sort out what wiring goes down to it.
