How hard?.. Heated leather seats
 

If I buy leather seat covers from clazzio, and then heated pads from this place, how hard will it be to wire them in? also will it be a huge power draw from car or will it be fine? I am worried that it could like fry the electrical system. Maybe I am over reacting, I am in alaska though and would be nice to have heated leather interior.

I was thinking simply- Put the heaters on the cloth seat bottom and back and then put seat cover over them so the heated pads in between the seats and leather, and run the wiring hidden and since its 12v i'll have to run it to the ciggarette lighter wiring connector correct? any advice/suggestions/pros/cons/concerns are appreciated
