No Brake Lights??

:Hey:First I would like to say Hello!
This is my first post.
I have a 1994 dodge 3500 with a Dump Bed. I have all of my lights but not my brake lights. I have replaced both flashers, because my hazards weren't working, and my brake light switch. But I still don't have any power, to any wire, in the rear when my brakes are applied. I have power at the switch. I am not opposed to running a wire from the switch to the rear. Also these are three wire lights gnd/rev/marker. Are the lights wrong? If so they were on the vehicle when I bought it and they worked then.

Thankz

So today I was playing with the problem and I disconnected the ground from the rear left turn light. Its all clipped together right now. I was holding the clip and twirling it around and my brake lights come on. So get this the left light is floating (not grounded) and when I moved the wire around it somehow magically turned the brake lights on. So I think I am having a back feed issue. Weird Shit Man.
Good Ground

Is it possible that the bulb socket gets it's ground through the frame? Do you have access to the wiring diagrams?

Here is the link to a download for the 1995 Service Manual. which I think is the same for the '94: https://docs.google.com/uc?id=0BwDkuRJfDNZEVVdHRkVFeTNmVUE&export=download
Tail Light Wiring

According to the '95 manual on page 8W-51-3, this is the function and colors of the wires on both of the tail lamps:
PIN 1: TURN/BRAKE DARK GREEN/BROWN
PIN 2: PARK BLACK/YELLOW
PIN 3: GND BLACK

Does anything work on either side now?
I'll keep looking for the backup.

Hot wire for the Backup light is VIOLET/BLACK
