hi you must have 3 wires to the socket
i've unmounted mine just to check and it's like this
3 wires
orange -> +12V (to the center of the socket)
brown -> +12V (to the side cilindric bulb)
black -> 0V ground (to the exterior of the socket)
Note: the colors may differ, but the socket and the socket's presence bulb share the same ground wire internaly, that's why there are only 3 wires visible.
usualy the black wire is standard for every car, and the light wire is thiner than the other two, since the black (ground) wire and the live 12V wire are thinker.
hope this helps =)
