What connection does the green and white wire go to the board?
The white and green wire are twisted together and i don't know if it's supposed to be like that but this device is (car aux adapter)(WT-AUX) and the iphone and aux cord ilare not working. An anyone help 
Pull up a schematic for the part on Google. That would be the safest bet.
The board? The board of what? If you're hacking the motherboard of your car stereo, you need a schematic. Get a "Sams Photofact" at the public library and it will show you everything.
