2005 SRT Crossfire. 1973 Euro 450SL
So I still have not taken my top off since I got the car last November, was looking at doing this in the spring, I see I have a cord on the right behind the pax seat, I guess this is power for the rear window defroster. but my rear window does not have the little wires like I've see in other cars. I do have a switch on the center dash with the heater symbol. Was the rear window heater an option?
