(On the Happy Days TV show Fonzie would hit the jukebox to get the music playing; just in case you didn't know....)
They are wired differently so there is an identifiable difference, but I can't just pick one up and identify what year it fits.

Connection problems where the instrument panel plugs onto the dash are common on these panels. Do not aggressively clean the connection or it may give you more problems. Some people say one use a pencil eraser to clean the panel contacts. My best luck with cleaning poor connections is to use very fine polishing paper and then very lightly grease them tuner cleaner lube.

I started building a list of numbers but don't have many. Here is what I saved:
