composite video mod from TFW8b should be straight forward from that point. The modulator connector is a good spot to pick up 0v (the black wire), 5V (the red wire) and video (the yellow wire). Audio is connected as shown above, to the right hand side of where R207 (the 18K resistor) was removed. The side not connected to the transistor.
Deluxe Composite Video Mod' used here is available from The Future Was 8 bit. See the previous blog post for some more examples of PAL Atari 2600 Composite Video Mods.
