OEM Heated Seat Swap

[euro96]

Hi Guys,

I have searched the subject of retrofitting heated seats, but everything is about installing kits.

My question is the following:

Can I take a set of BMW OEM heated seats and fit them into my X5 that currently has no heated seats, and make it work?
Of course I know I would need the switches, and some wiring, but it seems like there is not much too it?

Am I missing something big here? Is there an issue with making it work with the car's wiring harness?

I am thinking about buying a set of heated seats from a wrecked X5, or finding a member who would trade + cash my beige non-heated sport seats for any set of heated seats.
Just trying to figure out if the swap is feasible or not.

Thanks!!
