I've noticed most CB's seem to have the same plug for power, it this
an
industry standard? They all have a three pin plug with only the outer
pins used for power and ground, has the center pin ever been
used/defined?

The two closer together have always been ground.

Now they cheap out and only connect one?

Well, I haven't opened my new one yet, but the cheap radio shack one had
the
middle disconnected

I've seen the other pin used with a yellow wire that was supposed to be
tied hot at all times to retain the channel memory, but I forget what
model and brand that was.


Sounds like there isn't much of a standard then. I was wanting to use it
to
feed power in for the lights on the front and then use the dimmer knob for
the lights for something like a talkback circuit.

Feed the lights from the power switch and you can still use the dimmer for
talkback. If the center pin is not connected to anything (in most cases it's
not), you can still use it, but it will need to be switched or the lights
will remain on when the unit is off. I would go with using the power switch
to control your lights.
