In the second picture mate thats an autoleads cable
at the plug the cables should be.
Red +
Black -
Yellow is radio mute (if you earth it this should work)
Blue is ignition sense (u can test this with a test light)
You need a microphone
Handsfree control box
Cradle for the phone to charge, (unless bluetooth)
you have the power plug and the headphone jack that plug into the control box (the headphone style jack makes the sound come through your car speakers)
you still have to buy a car kit to fit your phone!
(ps that is for a nokia car kit judging by the plugs but its easy to cut off and join the other car kit plug on if you phones different!)
If you go for the bluetooth option then your tax disc antenna wont be used!

The plug you had would go in the white space on the box in the link, the headphone style one in the space over to the left, (the one beside is for the mic) you wouldnt need the speaker as you would be using you car ones, and the cradle plugs into the black box, and all you need then is to fit the mic!
Hope this helps!
