GunCon2 on PC-monitor

<EDIT TO REDUCE CONFUSION...
THE CIRCUIT PICTURED IN THIS POST IS THE WRONG CIRCUIT FOR A VGA MONITOR / WG D9200. I INCORRECTLY BUILT THE 15kHz (ARCADE) MONITOR CIRCUIT. IM LEAVING THE POST HERE FOR CONTINUITY, BUT THE CIRCUIT YOU NEED FOR VGA / WG D9200 IS NOT THE ONE IN THIS POST.
/EDIT To REDUCE CONFUSION>
OK....
I broke down and ordered the parts and built "the circuit".
Now, before I proceed, I have a question about hooking up this circuit between the VGA card and the monitor...
Here's my understanding of what I need to do now:
1. Cut a VGA cord into 2 parts
2. Find the wires corresponding to SGND (10), HSYNC (13) and VSYNC (14)
3. Solder a "pigtail" lead from each of the 3 identified wires to the appropriate input wire on the circuit board
4. Reconnect all of the wires in the VGA cable
5. Connect "Hacked" VGA cable between VGA card and monitor as per normal VGA cord
6. Use the Composite Sync output from the circuit to connect the GUNCONs
Did I get any of this wrong or leave anything out?
I'm just leery of messing up my monitor or VGA card.
In case it matters, the monitor is a 27" Wells Gardner D9200. The VGA card is an NVidea FX series.
I'd like to try this out tomorrow... but I'm looking for some assurance from the kind experts here first.
Thanks in advance!

tivogre, But isn't the circuit in the picture the one I used to connect the gun to a 15Khz VGA ? It is not what they are talking about here.
However I had better results sending the composite sync to the monitor from the same wire I use for to the gun instead of sending separate syncs to the monitor and composite to the gun ... maybe this helps you to.

OK Now I'm REALLY confused!
The circuit above is the one linked to from intruderalert's page with all the examples of "known working" connection methods.
http://intruderalert.myarcade.org/GUNCON2.htm#VGA
At the bottom of the section on VGA Monitors, he shows this picture; hacking the VGA cable into "the circuit" is where I think I am now.
Is this, or is this not what I need for my application?
If it is, do I have the correct method to USE the circuit listed out above?
Acorn:
In this case, I think he was reffering to the thread - this thread has been about a circuit to allow 31Khz monitors to work with the guncon2. The methods used in intruderalerts guide is to connect from a VGA out to a 15Khz monitor, which I believe is what yours is.
Cananas:
Silver,
I bought a jpac small chip to Andy and I built the circuit you post but it doesn't work for me.

Andy from Ultimarc has had his Namco2 guns working with the above circuit.

Sorry, but I don't know what this circuit do. Please Andy, could you explain us how it works?
Thanks.
PD. My guncon2 gun works perfectly with my TV both with the vga-scart with the sync circuit and TV out.
