There is a wire harness that runs from the truck lid and runs along the hinge. When you close the trunk, the cable harness gets pinched. Do to the age of the car, cables start to break by being pinched (open and closing of the trunk). Some of the wires have 12v for the rear brake lights. Noticed this when I started to have random rear brake light failures. Has anyone else have this issue? I would think this would be a common problem by the way it was designed. I just cut the cables several inches between where it was pinched and replaced it and made the cables little bit longer. I used solder and shrink tube and wrapped it with cable tape (fabric kind).
