The headlights go on when turn key on, this is not normal and won't shut off until car is shut off and key remove. Where is the headlight relay and diagram for car? Don't know if it the relay or headlight switch.

Hello, I'm Danny.

I have a question first. Is your car equipped with or without Xenon Lamps? When you get back to me I can provide with information and diagrams. Thanks for using 2CarPros.
