Tilt hopefully you can clear up some confusion on my end, for some reason I am missing a few lines because I either get no signal or it does not display correctly, the vga pinouts I have seen are all different.
hopefully you can help with the pins in question

Thanks

CLK and SDA are in question as to which pins on the vga plug they go to the colors are straight forward and the rest is for the touch controller which i did not mess with.
any help is greatly appreciated. I did one of these a LONNNNNG time ago I dont remember how I wired it and did not take notes OOOOPS

It sounds to me like you're trying to make a cable from the 25 pin beau plug on the monitor shelf to a VGA connector that plugs into the back of a LCD display?  The CLK and SDA lines are not needed or used.  The drawing I posted is for a CRT and J340 is the beau plug on the back of the monitor.  On the P340 side from the machine end those two signals are not even connected to pins 10 and 11. 

To make an adapter you need to use the red, green, blue, horz sync, vert sync, a ground.  That's all you need for the video signals.   Here's a VGA connector pinout I grabbed from google.  Make sure you look at the tiny numbers next to the pins and get the wires connected to the right ones.

Hope that helps.

That how I have it, sync is jittery, I will go over it again and see what happens …. Yes I am using an existing harness from the CRT

Thank you  for the insight
