I have a 2006 BMW 325i (4 dr). The brake pad light came on to replace REAR brake pads, so i did. However, when i went to replace the brake light sensor, i had trouble. When i took old one off and looked at the new one the BMW dealership gave me, they look different.

The old connection (sensor) to the back of the tire is thicker, probabaly a 1/2 inch thick. The new one is skinnier, probabaly 1/4 inch think.

The old sensor connector to tire looks like a cap to a magic marker, the new sensor connector to tire metal is exposed and looks as think as a ball point pen cap.

Am i replacing the right wire? Can anyone shed light on this? Much appreciated.
