Broncco TX-6 help needed

Finally bought and put a non-correct seat on my TX-6 and went for a spin. Runs well! Now I just need to work on the electrical system as I only have the coil straight-wired to the magneto. Want to get the lights and horn working. Does ANYONE have a wiring diagram or schematic for this bike? Even a description of the wire colors and where they go would work or pics of how the wiring is laid out on the bike would be helpful to me. Can any Broncco owners help me?
