Scroll about 4/5 of the way down the page until you get to the "Electrical" section. You will see four diagrams for the center console gauges.
You say your car had a console. Did it have gauges, or was it the earlier "center deposit" style? If it had gauges, were they wired up at all?
If they weren't wired before, you will need to find wires that carry the appropriate power/signal/ground. The wiring diagrams are your friend there. You'll find them in the Haynes manual, and you can probably find PDFs of them if you hunt around on line.
