The local Pick-N-Pull has a same-year Caprice with the optional instrument cluster which includes a temp guage, an "ecomomy" guage (measuring vacuum, I assume) and maybe even oil pressure.

Can I swap my standard guage cluster with this upgraded one and have the data get to these new guages? It's set in a circuit board with a wiring harness running eventually to the ECU. I'm hoping that since the ECU measures these inputs, the connection to the cluster will allow the new guages to work.

Any experience or advice would be greatly appreciated.
