Has anybody fitted heater pads to their existing interior?

I don't want to change my LE interior but would love heated seats on these cold mornings.

 

Is there a how to and list of parts I'd need for my pre fl VRS?

Retro fitting heated seats had been done and there was some detail about the parts needed (for a FL I think) and the process on here recently. I seem to remember that the worst bit was stripping down and then putting the seats back together!

Thanks guys, I did want to fit OE style but that kit seems a simpler way. I suppose could hide the controls in the arm rest.

Where did you fit your buttons?
