I just got a '92 4 cyl. LX hatch that needs the seats replaced. I picked up a full set of seats from a 8 cyl. LX fox, not sure of year, but the new seats have the lumbar support and the old seats don't. Will I find the wiring for these under the rug or somewhere or is there nothing there. If there is nothing there, where would I wire them in? Thanks... Chuck
