===== Xbox 360 AV Connector ====
Much like most post-Dreamcast consoles, the 360 has variable outputs depending on the status of the SELECT pins.  Some pins are always the same (digital audio) but others may be changed, enabled or disabled depending on the cable's SELECT status.  The select pins are usually called ID1 -  ID3, and those names are maintained here.

^Pin^Description^-^Pin^Description^
|  1  |GND (Red)|-|  2  |GND (Green)|
|  3  |Red / Component Pr / Svideo Y|-|  4  |Green / Component Y / Svideo C|
|  5  |GND (Composite)|-|  6  |GND (Blue)|
|  7  |Composite|-|  8  |Blue / Component Pb|
|  9  |GND (H Sync)|-|  10  |GND (V Sync)|
|  11  |H Sync|-|  12  |V Sync|
|  13  |GND (Audio R)|-|  14  |GND (Audio L)|
|  15  |Audio R|-|  16  |Audio L|
|  17  |[[av:scart_connector|SCART Switching]]|-|  18  |ID1|
|  19  |[[av:scart_connector|SCART Blanking]]|-|  20  |GND (ID1)|
|  21  |DDC CLOCK|-|  22  |ID2|
|  23  |DDC DATA|-|  24  |GND (ID2)|
|  25  |Audio (SP-DIF)|-|  26  |ID3|
|  27  |GND (SP-DIF)|-|  28  |GND (ID3)|
|  29  |+5V (SP-DIF)|-|  30  |Reserved|

** Mode Select Pins **
  * NC = Not Connected, GND = connected to ground

^ID1^ID2^ID3^Mode^
|NC	|NC	|NC	|No Cable connected     	|
|GND	|NC	|NC	|VGA    			|
|NC	|GND	|NC	|Composite AV   		|
|GND	|GND	|NC	|Optical/RCA Audio adapter	|
|NC	|NC	|GND	|Component AV HDTV mode         |
|GND	|NC	|GND	|S-Video mode   		|
|NC	|GND	|GND	|RGB / SCART    		|
|GND	|GND	|GND	|Component AV SDTV mode 	|

  * Pin 30 has a similar circuit to the other three ID pins so it might me a 4th ID pin.
  * It is assumed, but not proven, that H & V Sync are inactive except for VGA mode.  Composite video is used in SCART / RGB mode (does it need a sync stripper then?)
