As I replied to you via email, not sure what you mean??? The MAF has internal female 'socket' (not pins)???

If you mean the cable that 'plugs into the MAF, then that's part of the engine wiring harness and it SHOULD be replaced. . . you're wasting your time rebuilding that "arm" of the cable harness. If it fell apart, then the rest of the harness must be in bad condition!

Thanks for all the info,but i still need the color of the wires and their location in the plug.
thanks

the picture i posted gives not only color name, but the wires in the diagram are actually the corresponding color, and the pins are numbered.

5 YEBK = YELLOW AND BLACK

2 YERD = YELLOW AND RED

1 BN = BROWN WHICH IN MERCEDES IS GROUND

4 YEBU = YELLOW AND BLUE

3 YEVT = YELLOW AND VIOLET
