Vga wireing plz help!

[Jox43w]

iv just picked up a scart and vga cable to make my vga to scart cable but i dont have a multimeter and dont know which whire are for which.

i have red green and blue

then i have  light green pinky light red are theese red and green (return) or (ground)?

if so what colour would blue ground be?

im trying to match the cables to the pin numbers on the end i cut off but the very base has been kind of coated in a plastic shell which has all the wires stuck togeter and is really hard to tell but from what i can see pin1 on the vga is a black wire wtf??

plz healp been looking foward to getting this done

colours vary,get a multimeter so you don't have to guess-it will save you a lot of bother

so you cant just go by the colours? this would make sense as iv using a battry and my mouth to test which wires are which and the coulers so far arer completly wrong! lol

ok i follwed the wireing guide on this site and iv just tested it and im getting a very faint black and white picture?

well you have done something wrong,tv set to the correct input and correct scart?

everything on the tv is set rite iv checked the cable and it all seems good only thing i can thing is i didnt add any reesitors or addin voltages because i wanted to switch av manuly but iv heard people use a battry connected to pin 16 to make the tv switch rgb? how do i connted the barrty + and - wires both go to pin 16?

16=+
18=-

what are you making a vga to scart for,scart will only accept 15khz so unless you are giving a 15khz signal it will not work
