Newly acquired '04 TB and I'm still discovering all of the doo-dads and what-nots. Driver's seat is power, non-heated. Passenger's seat is manual, non-heated. This is the harness under the passenger's seat - a large black connector and a yellow connector - neither one plugged into anything. Same thing under the driver's seat except the black connector is plugged in. Am I correct in assuming the black connector is the power harness and the yellow connector is for heat? It seems obvious, but I'd like confirmation.
