Model year 2012 and newer may have heated seats as an option or come with heated seats from the factory. These cars will have an additional connector that was not present in the 2011 and older model cars. This connector is located above the seat near the door and plugs into a separate harness underneath the seat that leads back to the trunk area below the deck lid for power. You can confirm this is the case by looking for an additional harness with a few bare wires coming out of the rubber insulation.

The heated seats are operated by a dedicated switch located under the seat. This switch is often mounted on a plastic bracket and held in place by 2 or 4 screws. The wiring for this switch is a 2 wire harness that tends to be orange in color. This wire will run from the switch down to the wire bundle below the floor board and is secured by zip ties or tape wrapped around it . The wire bundle should have at least one connector already attached that plugs into another harness under the seat. Read More
