My Ride: 2006 325ci vert
My wiring harness has five connections: a + connection; a - ground, a connection to each ballast; and a fifth connection that I assume has to connect to one of the car's existing low beam bulb connection.

Also, to make the bi-xenon feature function, there are two leads coming from each projector - I assume these two leads tap into the + and - leads for the car's high beams.

If anyone can advise that would be greatly appreciated!
