THE WIRING HARNESS ON MY 1993 MERCEDES 400SEL IS DEFECTIVE. AFTER TALKING WITH A MERCEDES MECHANIC, HE INFORMS ME HOW IMPORTANT THIS HARNESS IS AND WHAT COULD HAPPEN WHEN IT FAILS. THE WIRES ARE CRACKING AND SPLITTING AND ARE DRIED OUT. THIS IS A VERY DANGEROUS CONDITION. AFTER DOING THE RESEARCH, IT WAS DISCOVERED THAT MERCEDES KNOWS THE HARNESSES WERE DEFECTIVE AND HAS CHOSEN TO IGNORE THE PROBLEM. NO INJURIES OR DEATH AT THIS TIME. *TR
