Where do i fit jump leads to a 323i?

To jump-start a BMW 323i, connect the positive (red) lead to the positive terminal of the dead battery and the other end to the positive terminal of the working battery. Then, connect the negative (black) lead to the negative terminal of the working battery and attach the other end to a metal ground point on the engine block or chassis of the 323i, avoiding the negative terminal of the dead battery to prevent sparks. Once connected, start the working vehicle, then attempt to start the 323i.
