I appreciate there are differences in the way the system works but technically speaking, what are the differences?
Is it just the interface unit in the cabin that is different? Are all the rest of the bits and bobs in the engine bay the same?
I assume that there must be a thermostat somewhere for the climate to work but the basic cooling system should be the same...

Just wondering about fitting climate to a P1.... Sti 5 body shell so I assume that there must be some scope for doing this
