i just got my hid conversion kit and i need to find out where to put the - and +, cause i unplugged the bulb and theres a clip with 2 black wires, one is solid black and the other is black and has a white line down the middle which is positive and negative?

 

in most cases solid black would be your ground and the the black with white strip is the postive. To know for sure you could test with a multimeter if have one.

 

^yep. black should be the negative ground and black/white strip should be positive. search a bit first if you don't have a multimeter to test with.
