EDIT: some of the years might be similar enough to combine into one drawing, but '77 probably shouldn't be one of those.
EDIT #2: and looking at your wiring diagram, the '78 doesn't have the external voltage regulator and it has slightly different alternator-to-dash and alternator-to-ignition-pack. Junk Yard Genius has a good write up for moving ignition/alternator/distributor/etc from '78 and later over to a '77 to eliminate duraspark components and the external VR. just FYI.
OK, that's good info. I have only worked on my 76, so I am sure there are some ignition and alternator changes. My 76 had the Prestolite ignition ( not anymore, fuel injected now), and I know later on they switched to the Motorcraft/Duraspark on the 360, maybe on the 304 also.
Hopefully the dash wiring can help spankyway rewire his dash. I do not have a 77 schematic, the 76 schematic is right out of the Jeep Factory manual for 1976, I do have the Chiltons manual also, but have not compared both side by side, although Chiltons does have one schematic for 76-79, so they must be close other than the alternator and iginition module.
