Do you have the top cover of the steering column off?
If so you should be able to see a white plug with 6 terminals and 4 wires.
The pink wire and the white wire go down to the fusebox area to a gray plug which is clipped to the top right hand corner of the fuse box.
There will be no corrisponding wires coming out of the front of this plug.
You need to extend these wires from the plug to the radio.
The easiest way to do this is to cut them off the back of the plug, connect them to some new wires and run these to the radio plugs.

With the auto leads adaptor there will be 2 plugs that match the one already fitted to the car.
Follow the instructions suppled with the auto leads adaptor to fit it inbetween the plugs fitted in the car and the socket on the back of your head unit or the plug that comes from the back of the head unit.
