i have a vanagon heated seat setup..  it includes, switch, upper column
housing, wiring, relays. the only thing i dont have is the heating element pads for
the seats.. (you have to completely remove your upholstry from your front
seats to install the element pads)   the element pads are basically just fabric
pads with wires in them, you can grab them out of any car that had heated seats
(audi, volvo, etc), they just basically lay under the upholstry, theyre not
even sewn into the padding.   if someone would like to take this  without the
heating element pads,  otherwise i can source some element pads..
