Adding heated seats to TV. Anyone done it? Can it be done?

I put these in my truck last year. I have cloth seats. I took the plastic panel off under my radio, drilled holes, and put both switches in there. The only part which takes some time is running the wire from the seats to the panel, under the carpet and removing part of the seat covers to put the pad underneath. These seats heat up fast and are hot. My wife has a Dodge Grand Caravan with heated, leather seats and my seats heat up quicker. I would install them again.
