no tail lights 72 valiant

i need your guys help.so my headlights,turn signals,brake,high beam,dome lights work but i got no tail lights.i checked my fuse box all the wires that lead to the headlight switch.and still nothing ,right when i put a new fuse in and i turn on my parking lights on the fuse blows out.i unplugged the tail light section of the harness by the left kick panel and tried a new fuse and as i pulled the switch to turn on the lights it blew out again...so i know for sure its not the sockets at the tail lights shorting out. the wierd thing is that sometimes the fuse doesnt blow out right away ,when it doesnt blow out i wiggle the wires by the fuse box and the headlight switch and they work fine . so i was glad they were working but then as i drive down a couple blocks the fuse blows out again:wack::wack:. ..can someone help me out?
