I have almost completed the swap, both were TBI. I have had problems with the rear hatch pull down. I found a used one and installed worked fine first couple of tries then stopped working. I also have a large red wire near the heater blower motor that is not hooked up. It is hot when switch is on, and looks like it had a small bulb or some type of glass in it, it has a black rubber end that looks as though you would push into a small hole and it would seal with the rubber. Any ideas?
