95 civic halo install. help please!!!!!!

i am trying to install the symminc halo headlights in a 95 civic. We have figured out where the headlights plug in, but there is on more plug that we dont know what to do with. the best i can figure we need to hook it to the switch, but we cant figure out where the plug is. please help

how what u mean??

in the harness that came with the kit, there are three plugs that look the same. two of the plugs have a blue, a white and a black wire coming out of them. the othere pug has a green, a brown and another color that i cant remember right of the top of my head. i have to assume the one that is different is for the switch but i dont know. any help is appreciated. thanks guysdan
