I had after-market units installed into my cloth seats for $250 (Cdn) a seat. I don't recall how much of that was labour/parts, sorry. Sounds like they are pretty easy to install yourself but I had a real issue with cutting holes in the center console of my brand new Jeep for the on/off/heat setting switches

. My dealership didn't have the same issues.
Hope this helps,
Mike
