famicom controller ports pinout

[clueless]

I've seen some photos of people modding their famicoms to accept regular nes controllers. Thinking of doing the same, as the position of the cable isn't really ergonomical for me. I've deceided to tap the signals from the controller ports, not the external db15 connector, but for some weird reason though, I can't find a correct pinout for the controller ports. I have only the data, latch and clock signals from the nesrgb installation guide (for player 1)

I did many Famicom controllers with nes cords to use them with nes, from what I know pins are the same, in controllers two colors wires are inverted and u have to put couple resistors but u shouldn't find any problem following the pinouts

Even snes controllers are pin compatible
