How to install replacement cigarette lighter in peugeot 306?

I bought a replacement 12v cigarette lighter for my 1998 peugeot 306 to power my ipod charger and the wiring is not the same. Is there any easy way to install this myself? Please help.|||There are only two wires to your lighter,which are power and earth.The power goes to the centre part of the lighter and the earth connection goes to the casing.A test lamp will show you the power wire and the other one will be the earth,hope this helps
