Jared:
Would it be possible to also add signal labels for each line to the diagram as well? Well, maybe not on the line itself, but by where you have them connected to each component...
So a +, -, Y+, Y-, C+, C-
Looking at the picture, I'm assuming that the line in the center of the coax audio, components, and composite connectors is the "+" signal, and the line to the left is the ground.
It just makes it easier for those that like to follow signals->components, instead of drawings showing where something should be hooked up, especially if working with non-standard looking components.
Your diagram is by far the easiest to follow - I've had trouble with some of the other text listings since it's hard to tell which way they number the pins and whatnot. Anyway, if you can add signal labels, that would be great.
