Hello. Has anyone done a successful installation of an aftermarket seat heater on an s40? I have a 2001, and I've been looking at this heater: http://www.warmseats.com/

I'm just not too sure about ripping the seat apart and then trying to figure out the wiring.

Any suggestions? Is this an easy do-it-yourself project? I'm pretty handy, but I wouldn't want to screw it up.

Thanks very much.
