I just recently bought a 2010 EVO X from a dealer and he said the previous owner put in aftermarket headlights and botched the wiring for them. I'm looking at putting new headlights on anyway. But did the factory headlights have HIDs or no?

 

The HID headlights were a factory option and had different harnesses than the halogen headlights. If the previous owner hacked up the harness, you'll be hard pressed to figure it out with any certainty. What other options does the car have?
