The wiring loom (it does both seats) is A203 540 30 05 - arond £30 - I think it connects to the seats, the fusebox (power) and the front SAM (control) - not 100% sure though

The switches is a different matter That row of switches which sometimes includes the heater switches is one block. Given the combinations possible theres about 50 possible part numbers

If I was changing mine i'd find one with *all* the switches - but my friendly dealer was to busy for me to try and work out what part that may be. I can guess that the price is astronomic, so head down the breakers yard if I was you.

The wiring harness goes from the switch row to the floor. It gets ground from a connection point in the floor and has a fuse at the end of the dashboard.

Thanks - I presumed it was more clever than that !
