Sorry for Delay in response. I ordered 2 kits off Amazon. Its a pad and the switches as well as relays. I have a 4 seater. I just pulled the staples out of the seat cover installed the pads then wired them in. They have high and low and work awesome. I have had them for 2 years and we ride year around in the snow and ice and stay pretty warm, Warm enough i just wear a sweatshirt most the time. I do have a full windshield on in the winter to help block the wind.
