I bought a wrecked 2008 Smart Fortwo and it has heated leather seats. My 2013 Fortwo has non heated cloth seats. I swapped the passenger seat with no issues. When I went to install the driver seat the 2013 had four connectors: 1 Blue, 1 White, 2 Yellows. The 2008 seat has 1 Blue, 1 White, 1 yellow. Neither of the two yellows on my 2013 will plug into the seat from the 2008. Any ideas?
