I have a 96 z28 and my brake lights don't come on. The spoiler light will come on when brakes are pressed but the main lamps don't. I swapped brake switch, bulbs, and brake fuse and same results. When turning on the parking lamps or headlights the bulbs come on so its not those. One thing i did notice was on the brake switch, there are 6 prongs. the only thing hooked up was the smaller two terminal connector. Is there suppose to be something hooked up to the four terminal connector? I could not find any loose harnesses or anything that would plug into the four terminal. Thanks for any help.
