Have a problem with taillights on my 1993 it has brakelight and no taillights or turn signals in the back and when you turn the lights on the brakelights quit working have everything in the front and have hazard lights checked all fuse and they good checked the wiring out of the light switch and have power just don't have power to main plug in the back under the truck

 

Is there a specific fuse for the missing lights? Test it by swapping with a similar fuse to be sure it's good.

I'd start at the back and work forward. It sounds like you have something disconnected in that circuit, maybe a corroded plug or a broken wire.
