I am looking to purchase this antenna. I am finding that Mercedes used this antenna, but instead of having loose connector wires, their unit has a black plug. Does anyone know if this plug can be cut off, wires exposed and hooked up? Also, does anyone know if there are any other differences.?

The model I need is cased fully in aluminum, including the access door. Some have a black plastic access door and I think that unit is for later models.

I appreciate the help!

Thanks.
