Expert Reply:
Yes, the P3 part # 90195 will wire right up to the 4 wire brake controller install connector you have on your 2018 BWM X3. The white of the controller runs to the ground circuit, the red to the stoplight circuit, the blue to the brake output circuit which runs to the trailer connector at rear of vehicle, and the black runs to 12 volt power.
You will have to cut off the harness on your BMW and use the attached diagram to wire to the brake controller.
