i have a well&gard monitor it has 6 pins (r,g,b...) and 3 pins(sync). i try to connect it from pc to arcade so cut vga cable i see a lot of wires in there red, green, blue, black, orange,and white are the wires that i used also there are pink, light blue, light green, and others wires.  Early this morning when i connect i got some pictures but they are all in red color and rolling vertically.  Does anyone know what could be the problem.  And also i don't have the original video connector so i just use the female crimp connector for pins. 
Thanks for any help or reply
