More likely than not that this vintage car [ 92-95] are going to slowly start showing wire insulation breakdown throughout the vehicle.
The first to show was the infamous engine harness.. that was accelerated failure and would most likely be due to under hood engine heat conditions.. Being bio-degradable insulation, it would make sense that they are all made of the same compounds and are degrading according to design time frame plans..looks like a matter of time ..sad..........wish their time frame was long enough to get some mileage out of the car...makes you wonder why you were so concerned in meticulously changing the oil and such....huh?????????
