I purchased a 4 plug to replace my 3 plug. I know the green is the gound. On the new 4 plug there are colors but on the old 3 plug they are all gray. How do I determine how to wire the 4 plug .

You put the red on left, white in center, black on right the green goes on any close cabinet screw, unless you see a screw marked ground hear,
