Well today my Tundra is getting black leather from the dealer I made them add it part of the deal on close I've had my truck a week and love it. I tried to get him to throw in heated seats and he said it would be $400 extra that's after the close and we already agreed on the leather. So I'm thinking I'm do it myself because today when I dropped it off I almost had him install the heated asked where the buttons would be and I thought about it and was like hell no! He wanted to install the heated buttons on the side of the seat I would be so annoyed if I can't see them or know the setting . So I've been researching and on eBay came across these. I might put them on the dash under screen or the left of steering column. Thoughts and suggestions please feel free to add. I don't like the little round ones I seen guys use and what the dealership adds found these nice square ones.
