Thanks Geof,
Our cars are actually very similar, I did have a 2006 car for a few years. Functionally the pcb appears to be are very similar with just a different form factor. They share the same two connectors and have the same pin outs as far as I can tell. On the early cars as you say the Caerbont Multi Function Unit is behind the dash whilst mine is in the engine bay under a cover next to the my ecu. This mod to remove the pcb really doesn’t affect the MFU. The MFU uses a microprocessor and CAN interface for controlling the instrumentation, that’s a future project….
So yes in principle this mod could be done on the earlier cars but the relay assembly might need to be packaged differently owing to the available space.
