Want to add cold weather package

[smokinjoes]

Brought a '01 s60 from texas to colorado and want to add the cold weather package. Heated seats at the very least. Anyone familiar with this possibility? I had to replace the lower heater element in our vr6 once so I am not worried about doing that part. I just hope the wiring harness is already there and that parts aren't $2000. The package is only $650 to add when you buy the car new but there is no way it could be that cheap for all the parts individually. Any suggestions would be appreciated. Also note that my bumper cover does not have the reliefs for the cute little headlight wipers that wife really likes.
