I recently noticed my 2004 Discovery S has the extra green/black wires behind the center console armrest plate. I purchased a new plate and switches from AB and they turn on, but the seats aren't warming up. Anyone know if there are elements in the seats? Do I simply purchase new elements and install them? If so, does anyone have instructions? Thanks!

 

are your seats leather or vinyl, if leather the elements are there, if vinyl they are not.
