There are two red wires (although one has a stripe on PIN 4)
I have a picture though this should help?

I experimented with the PIN by covering them with paper to block them
from making contact to see what would happen - results given on the
picture.
Also notice how some wires are thick and some are thin
Can anyone give further advice now based on this picture?
