Seat heating control unit location & additional wiring diags

[56Doc]

Does anyone know where the seat heating control units are please?

I suspect they’re in the seats but don’t know for certain.

im also trying to find wiring diagrams that show the ‘in car-off seat’ wiring  for the Seat heating, ventilation & massage functions.

I suspect it’s just supplies from fuse panels for heating & ventilation to either the BCM or the HVAC control unit and that the massage supply is the main seat 12v supply, so not extra. However,!

I was pointed towards the ‘vladgur.comk site for wiring but while very useful, it’s not easy to search!

 

cheers guys
