Did you check the fuse?
If it's good, I'd say you have a break in the wiring leading to the socket, or bad grounding. Sometimes doing things like replacing a switch can add resistance [from fresh material being used] to the circuit and accentuate a bad ground.
I can't provide you with any scans of a wiring diagram, but if you're talking about a 1988 pick up [which I'm guessing only because of your username- it would help us help you if you post the actual year and model], I can tell you that there will be one primary harness running to the tail lights and it will split from there for brakes/license plate/trailer wiring. I'd advise tracing the wiring from back to front and looking for any breaks or cracks in the insulation; and checking ground points, which should be around the rear of the truck.
