E53 4.4 2002 heated front seats
 

I am trying to work out if my car (comfort seats)has the front heated seats pre installed.
I have removed the passenger seat from the car ( it is the left hand seat on a UK right hand drive vehicle ).
Having removed the seat switch panel and surround I found protruding from the centre rear of the seat squab 2 wires - one blue and one white - which went to a box and reappeared and continued to the mains seat connector block.
I have attached a couple of photos.
Does this mean the seat is prewired for heat and just need a switch and wiring loom to be added.
Hope so as it will save a lot of hassle fitting the retro kit I have purchased.
Also if all it needs is the switch kit does anyone know the relevent part nos, any help with info re fitting would be appreciated.

If you search that part number on the module, it is the seat occupancy sensor mat module. Used to determine if the passenger airbag needs to deploy (i.e. someone is sitting in the passenger seat).

Many thanks, back to the retro kit then.
