silly question but what are you hoping to achieve from the swap? is it just for the heated seats? because they switch on from the Iris so as per above it would need some kind of coding or programing to add that to the Iris, if its for the electric adjustment, how often would you really need to use that? I can't have the powered seats in mine, i'm pretty tall and they are about an inch higher, if you are desperate for heated seats, there was company i spoke to who would take a standard seat apart and add heating elements as an after market with a switch down by the seat controls, but I thought i'd try it without for a bit and honestly once the engine heats up I never find i miss them.
