My car is a 2003 VY Calais, running the VZ Calais interior dash surround and much prefer the look of the VZ style binnacle gauges. Below are a couple of links I've discovered so far which would be helpful to me if my car was a VZ, but the VY cluster pin outs are different.

As I understand it, on the VZ the oil pressure data is on the bus and sent to the cluster, i'm not sure if this is the case for the VY - a wiring diagram for the VY cluster plug would help clear this up.
Any advice would be much appreciated.
This is the outcome i'm hoping for
