When I remove the wire harness should I include everything to the gauges? Would it work to just use the '89 instrument panel and gauges? Will the check engine light serve any purpose in the MS system? Thanks,BOTP

Check engine light - not used.

As for the rest of your question - hmm you would need to check the wiring diagrams for both vehicles. I don't have the info.
