A cable connector assembly (100) comprises a mating member (3) assembled with a plurality of contacts (33, 34), a printed circuit board (2), a cable (7) having a plurality of wires (71) and a strain relief portion (72), and a light pipe located (4) between the printed circuit board and the strain relief portion. The printed circuit board is attached with a LED (24), and the LED is electrically connected with the contacts. The printed circuit board defines a front surface, a rear surface and a cutout (23) extending through the front surface and the rear surface along a mating direction, and the LED is disposed behind the rear surface of the printed circuit board, the wires are extending through the cutout of the printed circuit board and soldered to the contacts in front of the printed circuit board.
