headphone jack question

[MarioOwnsAll]

Does anyone know how to install a headphone jack into the system? If you have a wiring diagram of how to install the headphone jack that would be greatly appreciated. Oh and one more question, I'm going to be having a built in controller but I want to have a normal controller port aswell, but I'm not sure how to wire both the built in controller and the controller socket to the player one pins on the board. Is there a switch I can get that will switch between the built in controller and the controller port?

Check that out It'll tell you the pinout of the ps1 screen (even though it's for snes)

And yeah, i think you can use a switch (or something) to switch... Shockslayer did that on one of his N64 portables I think. I'm too stupid to understand it.. though it's probably very obvious.
