This is what the service info for that year shows. They didn't have the nice layouts they do now. This does show what most of them do for both of the clusters they used. Notice that the layout was changed, it looks like the plug you have is from the second version as it has a yellow wire at the end of the connector. The numbers in the list on the picture image are the circuit codes not wire positions those are in the connector diagram, So that yellow wire is circuit 237 and goes to the seat belt warning light. Not hard to match up but the image is terrible.
