Okay this is a follow up to an earlier post I made.  Here is what I
wrote in it:

                    hi everyone,

                I have a 1989 chevrolet k 1500 4x4 truck.  Had some
work done on the
                       box recently (it was removed) and when i got
it back my tail lights
                       havent been working properly (the tail light
wires were frayed off about
                       five years ago when my upper shock mount broke
but were re-wired up and have
                       worked fine up until now). I have both running
lights, when i hit the brakes
                       the driver side brake light works but the
driver side reverse light comes on as
                       well, the other side has no brake light at
all.  When i put it in reverse, no reverse
                       lights work at all lol.  I checked the wiring
underneath.  everything appears to be wired
                       up (none loose or anything) and the ground
appears to be ok.  any ideas what the hell is
                       causing this to happen??

Okay, so tonight I replaced all of the old wires with new ones, re-
wired the ground and put new bulbs in the tail lights and guess
what???  They still aren't working right!!  As well, putting the right
side signal light on makes the left side reverse light blink???  I
replaced each wire at a time so no to mix them up when i was re-
wiring.  Really stumped right now.  only thing I can think of is that
the sockets in the tail light circuits must be bad and need replaced.
Anyone got any ideas suggestions??
