I decided to have Classic Aero install seat heaters. They come with a control button, relay and heat adjust on a harness. I decided to mount the controls in one of the side panels that Classic provides. I ran power with a Molex connector through the floor to come out inside the panel. The plugs for the seat go out under the panel to the back of the seats. The control, high/low, is mounted in the panel with an on/off switch mounted on the panel.
