I've installed a few of Fred's mods. They only do video, so you'll have to run the audio through a coupling capacitor (100 micro Farad, electrolytic) separate from the mod. It looks like your photo has the white wire as video in, yellow as video out, black as 5V common and red as ground. A good place to mount it is on top of the four ICs to the right of the RF box when looking at the board with the RF box closest to you. His mods are brighter than Murat's (the Turkish guy's), but they tend to be unstable when the screen features bright colors. I replaced the 20-22 Ohm resistor with a 66 Ohm resistor (two 33's in series) to make it work more like Murat's.
