“The engine wiring harness on my 1995 mercedes benz s420 has disintegrated. The wiring insulation is cracked and broken in many places, which has resulted in a non-operating condition. The car has stalled 3 times so far, in traffic, and will now not run at all. Apparently the wires have broken down due to the heat of the engine compartment. I believe the wires were not suitable for the application they were used for.”
