Are all bench seats wired with heating elements? I just took mine out and there are two sets of wires coming out of them, not connected though
I have. My very first w126 didn't have heated seats front or rear. The rear seat back and bottom did not have seat heaters nor did the doors have switches.Every seat I've seen so far has the wires. Its whether the car has the wiring and switches or not that makes it "complete". I've yet to see the seats without the wires in them, and one of my cars doesn't have the heated seat option.
