I want to add heated seats to my 2002 coupe. Does anyone know if the switch wiring is in the car or will I need to source them wiring for the switches from a salvage yard to add to myexisting harness. I have the switches, seat heaters and the seat heating harness with relay that is located in the seat frame. Thanks for any information and knowledge.

My guess is no, you'll need to add. It's not hard to do once you sort out the wiring diagrams and splice/ground points.

I added a rear wiper to mine and there wasn't any wiring for it, had to add it all.
