Electrical Issues Due to Degraded Engine Wiring Harness on Mercedes-Benz 600SEL

Problem Description and Possible Solution

The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

My body harness and engine harness both are failing due to the poor quality of the wire insolation used by Mercedes-Benz.
