So my old part number was 0025455205. This was evidently superseded by part number 0035452405 which is what was put in my car. The original was a nine pin and the new one is a ten pin. It seems like Mercedes has done this with a couple of different relays, where the new part has an extra pin. Anyone know why they keep adding the extra pins? Could this somehow have affected my radio? I know I'm eventually going to have to take the radio out and check the wires, but it was just such a pain in the butt the first time. Somehow the radio is now hooked in with the interior lights, but how could I have hooked into one of those wires. Those shouldn't really live behind the radio or have been hooked up to the old radio.
