The high mount stop light wires (two wires in one sheath), and window defroster wires (two wires in one sheath), connect directly to plug ends behind the grommets where the harnesses enter the D pillar. If you observe how things are assembled as you are taking the old wiring out, you will see how they should go back together. At the other end of the respective wiring, the high mount stop light has two spade ends that connect to the back of the stop light, while the defroster wiring needs to be spliced in to the leads coming off the grid on the rear window. Cut the existing ones 4 or 5 inches from where they are attached to the window and solder and shrink wrap the new ends to them.
