What does each of these do, I need to know the funtion of each wire.

if you have a automotive light bulb atatch one end to a ground and then go through the pins one by one with the other while the car is off. The one that lights up is the one you want turn the car on and make sure you still have juice. You should be able to find it that way.

dude I am saying test the pins to see which one has constant voltage. I don't know the Flippin color I think mine was yellow or orange.
