This isn't a european car,you won't have any error codes if a HID system is installed. No resistors or "black boxes" are needed.

I have both 07 and 08 electrical wiring diagrams in front of me. There are connections to the body ecu,but its for triggering the relays,not for directly powering the bulbs. The relays supply power to the bulbs,relays get power from the battery. So how would there be any error codes?

I can't upload pics @ work,but I'll post diagrams tonight if anyone needs a better explanation.
