I'm going to have to do some fairly serious rewiring. Well, not serious by some folks standards but enough for me. Anyway, I was checking on wire color codes because I'd like to try to stay to the standards. Also, I'll use tiewrap labels with sharpie writing to make sure I can follow things later. Anyway, I came across this table of color codes and thought I'd post them.

Also, are there any new standards that I should be aware of??
