Hello, We've recently acquired a 3 year old Renault Megane Auto (which we are very happy with so far). This model doesn't have heated seats, but when putting something under the seats, I noticed there are bundles of wires going to both seats. I can't think what these woule be for if not a heater. Is it possible to add the (missing) fuse and a switch, or is it necessary to add heater pads as well?
Thanks
