take a picture from the back of the headlight. that should help a lot.
but from what i can tell (going from left to right):
1. far left one goes to the angel eyes. you don't plug them anywhere. you need to cut off the end connectors and splice them into something.
2. i'm pretty sure it's just nothing. you don't need to use that.
3. the part for the ballast, the headlight connector from the car goes there.
4. that's your high beam plug
