Well I am not sure about this kit but they are plug and play in a way. My HID kit came with 2 male spade connectors like this one shown.
One for Positive and one for Negative. slide them into the headlight plug on your car and all is well. Now that is not my idea of plug and play. Plug and play means no wires or anything exposed to any elements period(not be able to be shorted out in any way) so I bought the H7 harness(an extra $15 shipped) and made it plug and play.
