Thats the kind of cable im kinda looking to make but i am trying to just go from usb 2.0 and twist and soldier whe other end so i need a color code for the cam . Im pretty sure if i twist both reds 12v + and both blacks 12v - to power transformer and then my yellow wire to video + and i was going to run a jumper wire from 12v- to my video - and thats to just a plain ol RCA but i really want to check it on usb if possible even if i have to run a seperate power supply . TYVM for your help everyone
