Thanks for the information. It certainly give me a pretty good idea of where to start. I received my service manual in the mail today and took a look at the instrument cluster wiring diagrams. It appears, that for 1985, the U (2.0L) engine was not available with full instrumentation, only the W and TBD engines.I'm hoping that this difference does not cause any complexities in the wiring. I'll do some more research and see if I can find any more information.

Thanks for all of your help and I'll keep posting my progress.
