I have a central locking pump/security sensor module. It is for the CROSSFIRE and carries the correct Mercedes Benz code on it. These are kind of hard to find some times. I'm asking $330 and includes the shipping. I believe this part normally is in the 400 to 500 dollar range. I just bench tested it (even though it's new) and it works just like it's supposed to. If interested PM me. thx, Lee
