What wire turns the heat on the 25-pin connector under the seat of 330ci ?

New member here.

I am trying to figure out what wire actually turns on the heated seat in the 25 pin connector under the seat in my 2005 330ci front seats. All of the power seat function work with Pin 13 & 14.

Pin 13: +12V (Red)
Pin 14: Ground (Brown)

I know most cars require grounding of a certain wire to enable the heat but I want to take chance and blow the module that is under the seat! Not sure if BMW uses a ground or +12V signal to turn on the heat. The seats are going in to another car.

I would really apprecaite if someone can let me know what turns the heat on ?

Thank you,


Waid
