Help!!! No lights in back!!

*Problem: No lights at ALL in the back of the truck.. tried reverse lights, brake lights, turn signals, hazards, NOTHING. Turn signal bulbs stay illuminated. Hazards come on, but not in the back.
*Possible cause could be the trailer wiring harness thingy back there, it was hanging down and I wrapped it around the frame, maybe the metal part touched the frame and short circuited? Or something?
*Checked the fuses.. WHY would all the lights not work? Wouldnt more than one fuse blow? I dont think any of the fuses for the lights looked blown but I could always be wrong and sometimes these things are hard to spot... and it was dark.

Please help guys. I didn't touch anything, don't know what would make -all- of these lights go out.

Ok, well here is what I've found out..
*hazard lights work fine
*has a trailer wiring harness installed, some of the wires have split connectors BEFORE the connectors to the tail lights, etc. One of the wires doesn't have a connector, the ground wire from the harness was installed into the ground wire where the insulation was cut from the wire and just wrapped around the bare wire and taped.. LOTS OF electrical tape back there.. ugh..
So, I'm guessing the end of the trailer harness wire kit thingy whatever the metal part hit the frame and caused a short circuit maybe? I dont know.. but what would cause the problem? All my fuses are -fine-... please help guys I have no transportation and I'm broke and I hope I didn't lose any chance of getting this job..
