Well, I'm trying to wire up a 1992 Buick Roadmaster instrument cluster, but can't find a wiring diagram. I can't find anything at the library and Autozone says the Haynes manual doesn't have it. I have a wiring diagram for a 1992 Caprice, but the colors don't look right. For example the Caprice has 1 brown wire on the cluster, but the Roadmaster has 3 brown wires and a brown/white wire.

Point me in the right direction.

you might be able to score that from your local dealer is someone doesn't have it
