“Electrical wiring harness using soy based insulation degrades thereby allowing wires to spontaneous and/ or intermittent shorts. This has caused extremely dangerous driving situations. Very difficult to troubleshoot unless and until one discovers insulation failure. This has been and is widely known to be a problem with this era of cars.
