I posted up in your other thread. The harness for the heating element in the touring seats should be there in your base model. For the record, the sport package does not have different seats. There are base model seats (cloth), Nismo model seats (older Nismo style or newer Recaros) and then there are touring package seat (leather/heated plus there's a special 40th anniversary model version that's all red).
