Hello,

Because HID assemblies are too expensive where I live. If I were to remove the old ballasts, there would be two wires each side. I believe one is a control wire and the other is 12V. How do I hook up wiring for both high and low halogen beams? Do I need relays in this case?
Thanks!

Hello,

I have included the headlight wiring diagrams so you can see how the system works and which wires to connect to your HID system.

Hello, thank you for the diagrams. Is the headlight 'ECU' for HID lights refer to the ballasts?

I believe so. Do you have a picture of the ballasts?
