Changing seat pad adding seat heater?
 

My 05 is shedding foam faster than the hair on my head is falling out. Going to order a new foam seat bottom from The Seat Shop on Ebay. While I'm in there I was thinking of adding a seat heater as I live in Alaska now. Anyone know what kind of headaches I might be getting into? Not sure if the electronics are already there or not. It's a XLT without power seats.
