As a vehicle ages, the wiring harness, which is responsible for transmitting electrical signals throughout the vehicle, starts to show signs of wear. One of the most common issues is the degradation of insulation. Over time, the insulation around wires becomes brittle and cracks due to prolonged exposure to heat, moisture, and UV rays. This degradation can cause exposed wires, which increases the risk of short circuits, electrical failures, and even fires. Older vehicles are more prone to such issues as their wiring has been subjected to years of wear and tear. Corrosion and Oxidation of Connections Another major concern…
