By the way, here's ClintiePoo's Male VGA cable for use with a SOG display:

By the way, to all that are wondering, YES, you CAN use NKPatcher v10-vga7 on v1.0/Conexant XBOX's, AND all 3 video modes work PERFECTLY with NKPatcher v10-vga7, provided your monitor supports those resolutions. (480p, 720p, and even 1080i)
For all those attempting to make this cable, here are some helpful links:

NOTE: Make sure you have a Conexant or a Focus video encoder before even trying this, as they are the only video encoders that are currently supported. But judging by your v1.4 XBOX, you probably have a Focus encoder, so you're good.

isee on your diagram you use "2 0.1uf Ceramic Capacitors, 1 470k Ohm Resistor" where do they go
and are they needed??
p.s where did you get the little black box from??? i want one!!!!

Be sure you can read schematics and solder well, as building this cable is not very easy. But be sure to check out Textbook's VGA Tutorial for a good diagram on how to do it.
Direct link to Textbook's VGA Diagram:
EDIT: By the way, this guy from a previous thread is selling ready-made cables just like mine, only they are manufactured and are colored blue, for $30 shipped. It might be a better option for you in the long run, I just like to make my own stuff.
To answer your previous question, no, those are the incorrect parts. Radio Shack has exactly what you need as far as capacitors/resistors. Be sure you get the exact ones that are noted in the above diagram.

Result = black screen.
I tryed everything and all I could get is by setting the cable as VGA cable instead of Component (that´s how the scheme shows) is once I load the bios everything in green tones except for games and applications which use 720x480 (ninja gaiden, xport emulators, xbmc).
Do I really need the real NTSC dashboard or is enough with setting my eeprom to ntsc?

Here is a guide on how to do it.
NOTE: This is NOT my tutorial, ProgScan/X-S/XboxHacker are the original authors.
----- Begin Tutorial -----
For the original ms xbox dashboard, open xboxdash.xbe(or whatever your MS dashboard executable is) in a hex editor:
Search for: C7 46 28 20 00 00 00
Replace with: C7 46 28 40 00 00 00, for progressive only
Replace with: C7 46 28 00 00 00 00, for auto selection; this auto switches to progressive scan when your hooked up to a progressive enabled monitor, or it will do interlace when hooked up to a interlace only tv. IMO, this is the best one.
----- End Tutorial -----
NOTE: The Junkmonkey IND BIOS does actually require the cable to be in VGA mode, not HD mode, as you've figured out. NKPatcher is the only one that uses HDTV mode instead. Also, the only games/applications that will work with a VGA cable are ones that support 480p and above. 480i games will NOT work. However, NKPatcher actually fixes this problem by forcing 480i games to display in 480p, thereby making ALL games/applications compatible. But this option is only available to softmod users.

EDIT: Yes, that LM1881N chip you linked to IS correct. Here's the other parts:
470k ohm resistor: (1)
0.1uf capacitors: (2)
LM1881N sync seperator IC: (1) - (This is the one you linked to earlier)
