yea, each headlight has H1 for the projector and H1 for the high beam, but they connected both the hight and low beam H1 bulbs in each head wired with a plug just like the H4 plug and plugs straight to the h4 plug in the car
So to put HID's in, you would have to just forget about the wiring they made , and just put the HID's straight to the projector and just rewire the high beam with a separate switch , what i did was that i plugged the HIDs straight to the headlight plug then rewired the hight beam to the fog light switch , and just made a new switch for the bottom fog lights,, look at my cardomain page
