Installing Projectors

i would assume that you would have to tap into the headlight wiring then find a plug that fit into the type bulb you are adding. i have wondered this when i saw them in the past. please post up the outcome i will be curious to know.
 
I got same lights, they should come with extra swtich for interior and I just hooked them straight up to battery, there just foglights built into headlights so you can put them on by themselves or with headlihgts etc.
