Heated Seats

Over the past couple of days I have been looking at another 530iA that I am interested in buying. From the pictures and description I acquired through a VIN decode, the car does not have heated seats. While that is not a huge deal, it is nice, especially when the car is parked outside. My current car does have heated seats and I was wondering if there was a certain group of wires I could look for to see if this newer 530i just needs the buttons or if it isn't wired for heated seats at all.

Thanks for your help.

Nevermind, looks like I won't be getting the other car afterall. Thanks anyway
