im working on a clk 350. the ABS/ESP light is on and i have no brake lights. i removed the panel under the steering wheel to check the switch. this is the location for the switch according to alldata. i accesed the brake pedal brakcet and theres a spot for the switch but no switch or wiring. obviously alldata is wrong or am i really missing something here
