Turtle turned me onto these a year ago and my wife's Grand has them. She bought me a set for Christmas last year and they are AWESOME!

I don't have this brand of seat heaters but I love the ones I got! My only complaint is that they take too long to heat up (about 10 minutes). Once they do it's a wonderful thing! Mine came with a complete wiring harness. All I had to do was take the covers off the seats to stick them to the foam cushions. I think it took me about 3 hours total, not counting the time it took to unbolt and bolt the seats back into the Jeep.
