Peppers (and Tomatoes) are not actually annuals, but perennials. They are
native to tropical climes and in those enviroments they can live for many
years. If they are brought indoors during the winter and kept in a
relatively warm and moist room they can be replanted in the late spring and
continue to thrive...

As to the yellowing...no idea...

I have a pepper plant in a 2 cubic ft container on my deck,
and something is not right about it because it's leaves are
starting to turn yellow. It used to be dark green, but it's
now yellowish green, so I assume it needs some fertilizer,
but I'm not sure if it needs mostly N, K, P or Fe and/or
some other trace element.

It was originally planted outside of my home in '99, but it
was dug up after the first frost, and it's been in the same
container ever since, either inside or outside, depending on
the weather.

This is a 4 year old annual?
