03 Rear Lights Rewire

Is it jsut the brake lights, or do turn signals not work as well? If it is just the brakes, you should check the pedal switch, make sure it is working. What you need to do is get a multi-meter and start testing. The switch. The fuse junction. See if you have power in, and power out from the fuse. You could have cut the line from the switch, it shorted when you cut it, and not, it wont pop the fuse because it isn't grounding out. Start there and work your way back.
