Default Intermediate harness questions

Hey everyone. Can anyone tell me if the ribbon harnesses that run from the fuse box to the rear interchange between years? Are they coded numerically? A guy local to me has several for sale, he's parted a bunch of 66-67 Pontiac A bodies over the years, but doesn't have the harnesses labeled. I did a few searches and couldn't find anything on part numbers. Thanks to anyone that can help me out.

Johnny

A quick glance at the Color enhanced wiring schematics between '66 & '67 I have show different colors of wires/sequence so I would be inclined to say NO.

Mike, thank you for the offer, but I have a guy locally that has about 20 of them. He always treats me very fair and even will let me return something if there's an issue. He just didn't label them over the years, but has found mostly 4 digits codes on them. Trying to see if there's a specific code I need for my 66 hardtop. Heck for all He and I know they could be date codes.

The ribbon is only for the rear lighting and fuel tank sender. I don't think optional equipment would be incorporated into it.
As an example, My Rear Speaker and Defogger both have separate power leads.
