Hey guys,

I have a '94 z71 stepside I am having electrical problems with. When I turn on my headlights, I lose brake lights and tail lights. Also when I press my brake pedal, my turn signal speeds up like I have a bulb blown. All fuses are good to my knowledge plus I don't think this could be a fuse since so many different circuits are involved. The stereo was stolen out of this truck before I purchased it but it looks like the factory wiring harness was left in the truck. I have not replaced the stereo as of yet. Could this be caused by the turn signal switch since all systems seem to run through this or something else? Any help would be greatly appreciated. Also, there is some aftermarket wiring in place for a stereo amp and a CB radio. I have visualized the wiring for these the best that I can and have not found any bare wires or shorts. Thanks again for the help.
