Hey guys I just swapped from an M52 to an M54B30. My speedometer doesn't work and my abs system doesn't work. I have an M3 rear end which comes with the blue wheel speed sensor and the car came with the grey speed sensor.

Who has completed the swap and what's the fix? I searched and could not find anything.
