The way the HIDs are hooked is through the Wiring harness off the Battery. The lines from down the passanger side past the battery and then relay is located there with three wires leading from it. One of blue aftermarkter connections that connects to the actual headlamp is now plugged into the conection on the wiring harness to provide the power connecting back to the relay which inturns powers the 2 lines leading to the ballasts.
The blue wire in the picture above in my first post, is only used on the passanger side of the car. And other ballast has the direct power connection from the harness.
I am personally thinking it is the ballasts. I know the Ground connection of the new relay is spotless, cause IF it was not? The lights would not even come on at all. I feel the problem involves the ballasts only.
I can try and scare up some photos of the new wiring harness if need to be. And in regards to your question BlackinBlack. I am not sure if it is connected the way you mentioned. As I said before. The wiring with the blue ends, in the above photo, are connected the lamps connection of the same type connection for the 9007 bulbs.
I hope I am explaining this right?
And to answer your other question Black. These are single bulb HIDs no duals or extending HIDs. Sorry forgot to add that.
