Hello, I recently bought on 03 Escalade. I was in the process of replacing the daytime running bulbs and noticed someone replaced the HID lights with regular lights. The sockets are wires into the harness.. Now, my question is where would the ballasts be mounted, just to see if they are still there. If everything is gone, does anyone know where I can get the parts needed? Does anyone have a wireing schematic? Thanks,Mike
