I'd just try matching up the colors and see if it works - some might just be extra for surround sound or something.

Is the TV or anything labled?
red & blue or white ??= left or right - sound
yellow is video

if cable box goes to TV then TV wires go to vcr

so tv video yellow goes out to vcr video in

oh here ya go this explains it better and has some pictures -
